Best Water Softener for Orlando, FL — 17 Things to Know BEFORE You Buy!

Written by Craig "The Water Guy" Phillips

1. The Local Water Problem in Orlando, FL

Walk into any Orlando hardware store and ask about water heater replacement — you'll discover a troubling pattern. Homeowners throughout Orange County are replacing 40-gallon water heaters every 6-8 years instead of the expected 10-12 years. The culprit isn't Florida's humidity or age of the homes — it's Orlando's 9.8 grains per gallon (GPG) water hardness systematically destroying heating elements and shortening appliance lifespans across the region.

Orlando's water originates from the Floridan Aquifer, a massive underground limestone formation that spans much of Central Florida. As groundwater percolates through this calcium-rich geological layer for decades, it dissolves substantial amounts of calcium carbonate and magnesium compounds. By the time this water reaches Orlando residents through the municipal system, it carries 9.8 GPG of dissolved minerals — officially classified as "hard" water by industry standards.

To understand what 9.8 GPG means in practical terms, imagine your water as a mineral-rich soup. Every gallon flowing through your Orlando home contains 9.8 grains (roughly 168 milligrams) of dissolved calcium and magnesium. These invisible minerals remain suspended until heat or evaporation triggers them to crystallize into rock-hard scale deposits throughout your plumbing system, appliances, and fixtures.

The financial implications extend far beyond inconvenience. Orlando households at 9.8 GPG typically spend an additional $800-$1,200 annually on what water treatment professionals call the "hard water tax" — extra detergent, premature appliance replacement, increased energy costs, and professional descaling services. For a typical Orlando home valued at $300,000-$400,000, untreated hard water represents a measurable threat to both property value and monthly operating costs.

The problem compounds during Orlando's hot, humid summers when air conditioning units work overtime and water heaters cycle more frequently. Higher temperatures accelerate calcium carbonate precipitation, meaning scale buildup occurs faster in July and August than during cooler winter months. Orlando residents often notice the most dramatic changes in water pressure and appliance performance during peak summer usage periods.

2. What 9.8 GPG Does to Your Orlando Home

At 9.8 GPG, calcium carbonate forms a concrete-like coating inside your water heater within the first 18 months of operation. This scale layer acts as an insulator between the heating element and water, forcing your unit to work 25-35% harder to achieve the same temperature. For Orlando homeowners, this translates to measurably higher FPL bills and accelerated component failure.

The calcite crystallization process begins immediately when Orlando's mineral-rich water encounters heat or evaporation. Calcium and magnesium ions, suspended invisibly at room temperature, bond rapidly to metal surfaces when water temperatures exceed 140°F. Inside your water heater tank, these deposits accumulate in concentric rings, gradually reducing tank capacity and creating hot spots that crack heating elements.

Orlando's older neighborhoods, particularly those built before 1980, face compounded challenges with galvanized steel plumbing. At 9.8 GPG, mineral deposits combine with iron corrosion to create thick, cement-like obstructions inside pipe walls. Homes in College Park, Thornton Park, and other historic Orlando districts often experience measurable water pressure loss within 5-7 years without water softening treatment.

Appliance lifespan reduction follows predictable patterns at Orlando's 9.8 GPG hardness level. Dishwashers typically require replacement after 7-8 years instead of 10-12 years, while washing machine pumps and control valves fail 30-40% sooner due to scale accumulation in internal components. Coffee makers, ice machines, and tankless water heaters suffer even more dramatic impacts — many tankless manufacturers void warranties entirely without documented water softening in areas exceeding 7 GPG.

The soap and detergent waste at 9.8 GPG creates an ongoing financial drain for Orlando households. Calcium and magnesium ions chemically react with soap molecules to form sticky, grey scum rather than cleaning lather. This forces Orlando residents to use 3-4 times more laundry detergent, dish soap, and shampoo to achieve basic cleaning results. For a typical Orlando family of four, this compounds into approximately $180-$240 in unnecessary soap and detergent costs annually.

Skin and hair effects become pronounced at Orlando's 9.8 GPG hardness level. Calcium ions strip natural moisture from skin and form microscopic deposits on hair shafts, leaving both feeling rough and dry. Orlando residents frequently report increased eczema symptoms, particularly during summer months when hard water combines with chloramine exposure during longer, more frequent showers.

Laundry suffers visible damage at 9.8 GPG as mineral deposits embed permanently in fabric fibers. White clothing turns grey and stiff, while colored fabrics fade prematurely due to soap scum preventing proper rinsing. Scale etching on dishwasher interior glass becomes irreversible after 12-18 months of 9.8 GPG exposure, creating permanent clouding that reduces appliance resale value.

The cumulative annual "hard water tax" for Orlando households at 9.8 GPG typically ranges from $950-$1,350, combining increased energy costs ($240-$320), soap waste ($180-$240), appliance depreciation ($350-$500), and professional maintenance services ($180-$290). This represents a measurable monthly expense that compounds year after year without treatment.

3. Orlando's Specific Contaminant Profile

Beyond the 9.8 GPG hardness baseline, Orlando residents contend with a complex three-layer water chemistry challenge: chloramine disinfection, naturally occurring fluoride, and geological iron deposits. Each contaminant interacts with Orlando's mineral-rich water in ways that compound the basic hardness problem.

Chloramine in Orlando's Water

Orlando's municipal water system uses chloramine as its primary disinfectant — a combination of chlorine and ammonia that provides more stable, longer-lasting protection than chlorine alone. Unlike simple chlorine, which dissipates quickly from treated water, chloramine remains active throughout Orlando's extensive distribution network, ensuring consistent disinfection from the treatment plant to your home's faucets.

At Orlando's 9.8 GPG hardness level, chloramine creates compounding challenges. The chemical stability that makes chloramine effective as a disinfectant also makes it significantly harder to remove than standard chlorine. Scale deposits from hard water provide protected surfaces where chloramine can concentrate, intensifying the characteristic "band-aid" or medicinal odor that Orlando residents often notice, particularly in enclosed spaces like bathrooms.

Chloramine can react with lead in older plumbing systems, a particular concern in Orlando's historic neighborhoods where pre-1986 solder and fixtures may be present. The EPA maintains a maximum residual disinfectant level of 4.0 mg/L for chloramine, and Orlando's levels typically remain well below this threshold at 2.0-3.2 mg/L. However, the combination of chloramine and calcium scale creates an environment where lead leaching can occur in susceptible plumbing systems.

Standard water softeners do not remove chloramine. Orlando residents dealing with both 9.8 GPG hardness and chloramine taste/odor concerns require a two-stage approach: ion exchange softening paired with a catalytic carbon whole-house filter specifically designed for chloramine reduction.

Fluoride in Orlando's Water Supply

Orlando adds fluoride to municipal water at approximately 0.7 mg/L, following CDC recommendations for dental health protection. This fluoride enters the system as a controlled additive at the water treatment plant, not as a natural geological contaminant from the Floridan Aquifer.

The interaction between fluoride and Orlando's 9.8 GPG hardness is minimal from a treatment perspective — fluoride does not precipitate with calcium or magnesium under normal household conditions. However, residents concerned about fluoride consumption should understand that standard ion exchange water softeners do not remove fluoride from drinking water.

Orlando's fluoride levels remain well below the EPA maximum contaminant level of 4.0 mg/L and the secondary aesthetic standard of 2.0 mg/L. The intentional 0.7 mg/L dosage targets the optimal range for dental benefits while minimizing aesthetic concerns. Orlando residents seeking fluoride removal for drinking water purposes should consider a reverse osmosis system at the kitchen tap in addition to whole-house water softening.

Iron in Orlando's Water

Geological iron from the Floridan Aquifer appears intermittently in Orlando's water supply, particularly in areas with older distribution pipes or during periods of system maintenance. This iron typically presents as ferrous iron — dissolved, colorless, and tasteless until oxidized by exposure to air or chloramine.

At Orlando's 9.8 GPG hardness level, iron creates compounded staining problems. When ferrous iron oxidizes to ferric iron (the visible red-orange form), it bonds with calcium deposits to create persistent, difficult-to-remove stains on fixtures, laundry, and dishware. Even low levels of iron — 0.2-0.4 mg/L — become problematic when combined with 9.8 GPG of hardness minerals.

Iron concentrations above 0.3 mg/L can foul water softener resin, reducing the system's effectiveness and requiring more frequent regeneration cycles. The EPA secondary maximum contaminant level for iron is 0.3 mg/L, based on aesthetic rather than health concerns. Orlando residents in areas with recurring iron staining should consider an iron-specific pre-filter upstream of their water softener to protect the resin and prevent compounded staining issues.

The SoftPro Elite HE system is designed to work downstream of iron filtration when needed, but iron removal requires specialized oxidizing media that standard softener resin cannot provide.

4. Why Most Orlando Homeowners Pick the Wrong Softener

Drive through Orlando's established neighborhoods and you'll spot a troubling pattern: undersized water softeners struggling to keep pace with 9.8 GPG demand. Many Orlando residents fall into predictable purchasing mistakes that leave them worse off than before installation — wasting money on systems that can't handle the city's specific water chemistry challenges.

The biggest mistake Orlando homeowners make is buying based on price alone, ignoring grain capacity requirements for 9.8 GPG water. A 24,000-grain unit that might work adequately in a soft-water city will exhaust its resin in 2-3 days when facing Orlando's mineral load. The result: frequent hard water breakthrough, constant regeneration cycles, and salt consumption that quickly exceeds the "savings" from buying a cheaper unit.

Orlando residents frequently confuse water softeners with water filters, expecting one system to address both 9.8 GPG hardness and chloramine taste concerns. Softeners use ion exchange resin to remove calcium and magnesium — period. They do not reliably remove chloramine, fluoride, or iron. Orlando households dealing with both hardness and taste issues need a two-stage approach: softening for mineral removal, plus specialized filtration for chloramine and other aesthetic concerns.

The grain capacity math mistake costs Orlando homeowners thousands in premature system replacement. The formula is straightforward but critical: household members × 75 gallons per day × 9.8 GPG = daily grain demand. A four-person Orlando household generates 2,940 grains of hardness daily (4 × 75 × 9.8). Without proper capacity planning, undersized systems regenerate every 1-2 days instead of the optimal 5-7 day cycle, accelerating resin degradation and increasing salt costs.

Salt efficiency oversight compounds into major expense at Orlando's 9.8 GPG consumption rate. Older, inefficient softeners use 12-18 pounds of salt per regeneration cycle, while high-efficiency units accomplish the same resin cleaning with 6-8 pounds. Over 10 years in Orlando, this difference represents $800-$1,200 in unnecessary salt purchases, plus the labor cost of more frequent tank refilling.

5. The SoftPro Elite HE: Built for Orlando's Water

After evaluating Orlando's water hardness of 9.8 GPG and the presence of chloramine, fluoride, and iron in the local supply, one system consistently rises to the top for Orlando homeowners: the SoftPro Elite HE Water Softener. This isn't marketing preference — it's engineering logic applied to Orlando's specific water chemistry challenges.

The SoftPro Elite HE uses true salt-based ion exchange, the only technology capable of reliably handling Orlando's 9.8 GPG mineral load. Salt-free systems marketed as "conditioners" or "descalers" attempt to change calcium crystal structure rather than removing minerals from water. At 9.8 GPG, these alternative approaches cannot prevent scale formation. The SoftPro's cation exchange resin physically replaces every calcium and magnesium ion with sodium, delivering genuinely soft water that measures under 1 GPG after treatment.

Demand-initiated regeneration (DIR) becomes operationally essential at Orlando's 9.8 GPG consumption rate. Traditional timer-based systems regenerate on fixed schedules regardless of actual resin exhaustion, leading to either hard water breakthrough (under-regeneration) or salt waste (over-regeneration). The SoftPro Elite HE monitors actual water usage and mineral removal, triggering regeneration only when resin capacity is genuinely depleted. For Orlando households consuming 2,940 grains daily, this precision prevents the breakthrough episodes that damage appliances and create spotting problems.

NSF/ANSI Standard 44 certification verifies the resin meets performance and materials safety standards — critical for Orlando residents already managing chloramine exposure. This certification confirms the softening process itself doesn't introduce additional contaminants or interact negatively with Orlando's chloramine disinfection system. Given the complexity of Orlando's water chemistry, knowing each treatment component meets independent safety standards provides essential peace of mind.

The SoftPro Elite HE offers grain capacity options (32K, 48K, 64K, 80K) that properly match Orlando household sizes to 9.8 GPG demand. For a typical four-person Orlando household generating 2,940 grains daily, the 48,000-grain model provides optimal 7-day regeneration cycles. Smaller households can choose the 32K model, while larger families or homes with high water usage benefit from 64K or 80K capacity to maintain efficient regeneration timing.

The 10-year warranty protects Orlando homeowners during the years of highest hardness stress. At 9.8 GPG, softener resin processes nearly 400 pounds of calcium and magnesium annually per household member. This heavy mineral load represents significant wear compared to soft-water regions. A decade-long warranty coverage provides financial protection during the period when Orlando's water hardness creates the most demanding operating conditions.

The SoftPro Elite HE's compatibility with iron pre-filtration addresses Orlando's intermittent iron challenges without voiding warranties. The system is specifically designed to operate downstream of iron removal media, preventing resin fouling that would otherwise shorten service life when Orlando's geological iron levels spike during aquifer changes or distribution system maintenance.

Self-cleaning sediment pre-filtration protects the primary resin tank from particulate damage — important in a city where both sediment and 9.8 GPG hardness stress system components simultaneously. Before hardness minerals reach the expensive ion exchange media, suspended particles are captured and periodically backwashed away, extending resin life and maintaining consistent soft water output.

For Orlando households dealing with 9.8 GPG of water hardness and the compounding presence of chloramine, fluoride, and iron, the SoftPro Elite HE is not a comfort upgrade — it is infrastructure protection for your home.

6. How to Size Your Softener for Orlando

Proper sizing for Orlando's 9.8 GPG water requires precise calculation — guesswork leads to either undersized systems that can't keep pace or oversized units that waste salt and water. Follow this step-by-step formula to match your household's actual demand to the right SoftPro Elite HE capacity tier.

Step 1: Count household members (include all regular residents)

Step 2: Multiply by 75 gallons per person per day (national average accounting for all household water use)

Step 3: Multiply household gallons × 9.8 GPG = daily grain demand

Step 4: Multiply daily grains × 7 = weekly grain demand

Step 5: Add 20% buffer for high-usage days (guests, laundry days, lawn watering)

Step 6: Match result to SoftPro Elite HE grain capacity (32K / 48K / 64K / 80K)

Here's the calculation worked out for a typical four-person Orlando household:

4 people × 75 gallons = 300 gallons daily

300 gallons × 9.8 GPG = 2,940 grains daily

2,940 grains × 7 days = 20,580 grains weekly

20,580 + 20% buffer = 24,696 grains weekly capacity needed

This Orlando household requires approximately 25,000 grains of weekly capacity, making the SoftPro Elite HE 48K (48,000 grains) the appropriate choice. This provides comfortable 7-day regeneration cycles with reserve capacity for high-usage periods.

Regenerating every 5-7 days optimizes both resin life and salt efficiency at Orlando's 9.8 GPG hardness level. More frequent regeneration wastes salt and water, while longer cycles risk hard water breakthrough that defeats the entire purpose of softening. The 48K capacity allows this Orlando household to maintain peak efficiency throughout the system's service life.

7. Installation in Orlando: What to Know

Orlando requires licensed plumber installation for water softener systems that connect to the main water line — this isn't optional bureaucracy, it's code enforcement that protects your home's plumbing integrity. Orange County building codes mandate professional installation to ensure proper backflow prevention and drain line compliance with local regulations.

Proper placement follows municipal standards: after the main shutoff valve and water meter, before the water heater and any branch lines. In Orlando's typical concrete block construction, this usually means installation in the garage or utility room where main lines enter the house. The softener must treat all household water except outdoor irrigation lines, which should remain on hard water to avoid salt damage to landscaping.

Drain line requirements for regeneration discharge must comply with Orlando's municipal codes. The SoftPro Elite HE backwashes approximately 40-50 gallons during each regeneration cycle, carrying dissolved calcium, magnesium, and salt to an approved drain. Most Orlando installations connect to a utility sink, floor drain, or dedicated standpipe — never directly to septic systems or areas where discharge could affect foundation stability.

Orlando's typical municipal water pressure ranges from 45-65 PSI, well within the SoftPro Elite HE's operating specifications of 25-80 PSI. However, homes in newer developments like Lake Nona or Winter Garden may experience higher pressure (70+ PSI) that benefits from a pressure reducing valve upstream of the softener to prevent component stress and extend service life.

At Orlando's 9.8 GPG hardness level, use evaporated salt pellets exclusively — solar crystals leave excessive brine tank residue at high regeneration frequencies. Evaporated pellets provide 99.8% purity, minimizing the tank cleaning required when regenerating every 5-7 days. The higher cost per bag is offset by reduced maintenance labor and longer system life in Orlando's demanding conditions.

Check salt levels monthly at Orlando's 9.8 GPG consumption rate. A 48K system serving a four-person household will consume approximately 40-50 pounds of salt monthly, requiring refilling every 6-8 weeks depending on brine tank size. Set a calendar reminder — running out of salt allows hard water breakthrough that can damage recently cleaned appliances within days.

8. Maintenance Schedule for Orlando Homeowners

Orlando's 9.8 GPG hardness creates high salt consumption and accelerated system wear, demanding a proactive maintenance schedule that prevents small problems from becoming expensive failures. Follow this calendar precisely to maximize your SoftPro Elite HE's service life in Central Florida's challenging water conditions.

Monthly Orlando Maintenance (Every 30 Days)

Check salt level and consumption rate — at 9.8 GPG, salt usage runs high and requires consistent monitoring. A properly functioning system should consume 40-60 pounds monthly for a typical Orlando household. Significantly higher consumption suggests resin fouling or incorrect regeneration settings; lower consumption may indicate system bypass or control valve problems.

Inspect for salt bridges — a hard crust that forms above the brine water line, blocking proper regeneration. Orlando's high humidity can accelerate bridge formation, particularly during summer months. Break any bridges with a broom handle and adjust salt type if recurring problems develop.

Verify the bypass valve remains in the service position. Orlando residents sometimes accidentally switch to bypass during plumbing work or maintenance, allowing 9.8 GPG hard water to circulate through recently cleaned appliances and fixtures.

Quarterly Orlando Maintenance (Every 90 Days)

Clean the brine tank thoroughly, removing salt residue and any accumulated sediment. At Orlando's regeneration frequency, mineral buildup accelerates compared to soft-water cities. Empty the tank completely, scrub walls with mild detergent, and rinse thoroughly before refilling with fresh evaporated pellets.

Test post-softener water hardness with a reliable test strip — confirm output remains under 1 GPG. Any reading above 1 GPG indicates resin exhaustion, incorrect regeneration timing, or possible system bypass. Address immediately to prevent scale damage to protected appliances.

Inspect and clean the sediment pre-filter if iron staining has occurred in Orlando's supply. Iron fouling accelerates during summer months when aquifer conditions change. Replace filter cartridges showing orange discoloration or significant pressure drop.

Annual Orlando Maintenance (Every 12 Months)

Complete brine tank disassembly and cleaning, including float mechanism and control connections. Orlando's high mineral processing load creates more residue than typical installations. Annual deep cleaning prevents float sticking and control valve problems that could cause flooding or regeneration failure.

Conduct resin bed performance evaluation by testing hardness removal efficiency. If post-softener water exceeds 1 GPG despite proper salt levels and recent regeneration, resin may require cleaning or replacement. At 9.8 GPG processing load, resin degradation occurs faster than in soft-water regions.

Audit regeneration cycle timing and salt dosage to confirm optimal efficiency. Orlando's seasonal water usage patterns may require adjustment — higher summer consumption often benefits from shorter regeneration intervals, while winter usage may allow longer cycles.

Five-Year Orlando Maintenance

Evaluate complete resin replacement based on performance testing and visual inspection. At Orlando's 9.8 GPG processing load, resin typically maintains effectiveness for 8-12 years, but annual testing after year five helps predict replacement timing and budget accordingly.

9. Is Orlando's water at 9.8 GPG dangerous to drink?

Orlando's 9.8 GPG hard water meets all EPA safety standards for drinking water — the minerals causing hardness are calcium and magnesium, both essential nutrients that pose no health risks at these concentrations. The "hard" classification refers to soap interference and scale formation, not toxicity or contamination.

However, Orlando residents with kidney stone history should consult healthcare providers about calcium intake from water sources. Some individuals benefit from reduced mineral consumption, though the calcium in Orlando's water represents a small fraction of typical dietary intake.

10. Will a water softener remove chloramine from Orlando's water?

Standard ion exchange water softeners, including the SoftPro Elite HE, do not remove chloramine from Orlando's municipal water supply. Softeners target calcium and magnesium hardness minerals exclusively. Chloramine removal requires catalytic carbon filtration specifically designed for this stable disinfectant compound.

Orlando residents concerned about chloramine taste and odor should install a catalytic carbon whole-house filter upstream of their water softener. This two-stage approach addresses both hardness and aesthetic concerns effectively.

11. How much salt will I use per month in Orlando at 9.8 GPG?

A typical four-person Orlando household at 9.8 GPG will consume approximately 45-55 pounds of salt monthly with a properly sized SoftPro Elite HE system. This equals roughly one 50-pound bag every 4-5 weeks, costing $6-$8 monthly in salt purchases.

Higher consumption suggests system problems or incorrect sizing. Lower consumption may indicate bypass operation or regeneration failure — both requiring immediate attention to prevent hard water damage.

12. Does Orlando require a permit to install a water softener?

Orange County requires licensed plumber installation for water softeners connecting to main water lines, but separate permits are typically not required for standard residential softener installation. However, regulations change periodically, and installation must comply with current plumbing codes.

Check with Orange County Building Department for current requirements, particularly if installation involves electrical connections or significant plumbing modifications beyond standard softener placement.

13. Why does soft water feel slippery in Orlando showers?

The "slippery" sensation occurs because soft water allows your skin's natural oils to remain intact, rather than being stripped away by calcium ions. Orlando residents accustomed to 9.8 GPG hard water often interpret this normal, healthy skin condition as "slippery" or "slimy."

This adjustment period typically lasts 7-14 days as your skin and hair regain natural moisture balance. The sensation indicates the softener is working properly, removing the minerals that previously interfered with soap effectiveness and skin hydration.

14. How quickly will I see results after installing a softener in Orlando?

Orlando residents typically notice immediate improvements in soap lathering and reduced spotting on dishes and glassware within the first 24-48 hours of operation. However, reversing existing scale damage takes longer — water heater efficiency improvements develop over 3-6 months as existing deposits gradually dissolve.

Skin and hair improvements usually become apparent within 1-2 weeks, while appliance performance gains manifest over several months as scale deposits clear from internal components.

15. Can the SoftPro Elite HE handle Orlando's water without additional filtration?

The SoftPro Elite HE effectively addresses Orlando's 9.8 GPG hardness and intermittent iron issues, but chloramine taste/odor concerns require additional catalytic carbon filtration. Fluoride removal, if desired for drinking water, requires reverse osmosis treatment at the tap.

Most Orlando households benefit from the softener alone for hardness control, adding specialized filtration only if taste, odor, or specific aesthetic concerns warrant the additional investment and maintenance.

16. What happens if I don't treat Orlando's 9.8 GPG water?

Untreated 9.8 GPG water will reduce water heater efficiency by 30-40% within two years, increase appliance replacement frequency by 35-50%, and create permanent scale damage throughout Orlando plumbing systems. The cumulative cost typically exceeds $1,000 annually in energy waste, premature replacements, and maintenance services.

Scale damage to fixtures, appliances, and plumbing is largely irreversible once established, making prevention through water softening far more cost-effective than attempting repairs after damage occurs.

17. Final Verdict for Orlando

Orlando's water hardness of 9.8 GPG demands professional-grade treatment — this isn't a minor inconvenience, it's active infrastructure damage occurring daily in unsoftened homes throughout Orange County. The combination of geological hardness from the Floridan Aquifer, chloramine disinfection, and intermittent iron creates a water chemistry profile that systematically shortens appliance lifespans and increases household operating costs.

The SoftPro Elite HE rises above competing systems because its demand-initiated regeneration, NSF-certified resin, and iron-compatible design directly address Orlando's specific challenges. The 48,000-grain capacity provides optimal efficiency for typical Orlando households, while the 10-year warranty protects your investment during the years of heaviest mineral processing demand.

For Orlando residents ready to stop paying the hidden hard water tax, check current SoftPro Elite HE pricing and available grain capacities for your household size. The system's engineering matches Orlando's water chemistry demands, providing measurable protection for appliances, plumbing, and monthly utility costs.

After 15 years of covering municipal water systems from the Everglades to Lake Apopka, Orlando's 9.8 GPG hardness represents one of Central Florida's most predictable and solvable homeowner challenges — but only when addressed with properly engineered equipment rather than wishful thinking.
