Converting from a traditional tablet-chlorinated pool to a salt water pool is one of the highest-satisfaction upgrades in pool ownership. Salt pools produce their own chlorine on demand from dissolved salt, eliminating the weekly tablet refill, smoothing out chlorine swings, and producing water that feels softer to skin and easier on eyes.
Converting from a traditional tablet-chlorinated pool to a salt water pool is one of the highest-satisfaction upgrades in pool ownership. Salt pools produce their own chlorine on demand from dissolved salt, eliminating the weekly tablet refill, smoothing out chlorine swings, and producing water that feels softer to skin and easier on eyes.
This guide is the complete WETYR Pools reference on salt water conversion. The process is mechanical (install a salt chlorine generator at the equipment pad), chemical (dissolve salt to the right concentration and balance other parameters), and procedural (start the system, calibrate output, and tune for your specific pool).
If you would like WETYR Pools to handle the conversion, we install, commission, and provide ongoing service across our maintenance markets. We carry the leading salt generator brands (Pentair IntelliChlor, Hayward AquaRite, Jandy TruClear) and quote a fixed itemized proposal that includes hardware, install, salt, chemistry, and a one-year service follow-up.

Salt water pools are still chlorine pools. The difference is how the chlorine is produced. Instead of dropping chlorine tablets into a floater or in-line chlorinator, you dissolve pool-grade salt (sodium chloride) into the water to a concentration of about 3,000 ppm (less salty than tears, about one-tenth the salinity of seawater). A salt chlorine generator installed in the equipment pad runs water through a titanium cell coated with precious metal; an electrical current splits the salt into sodium and chlorine, releasing chlorine into the water. The chlorine sanitizes, then recombines back into salt and the cycle continues.
The result: a steady, gentle chlorine residual produced on demand, no tablets to handle or store, less chlorine smell, and water that feels softer because of the dissolved salt. The salt does not get 'used up' (it is recycled chemically); you only add salt to replace what is lost to splash-out, backwash, and rain dilution, usually a couple times a year.
Salt pools still need every other normal chemistry parameter balanced: pH, total alkalinity, calcium hardness, cyanuric acid (60 to 80 ppm in salt pools per generator manufacturer guidance). The cell itself needs cleaning every 3 to 6 months (a vinegar or muriatic acid soak to dissolve calcium scaling). Cells last 3 to 7 years with normal use, $400 to $1,200 to replace.
Lower ongoing chemical cost: salt is cheap ($5 to $10 per 40-pound bag). A typical salt pool uses 4 to 8 bags per year. Tablet pools spend $300 to $600 per year on tablets. After break-even (2 to 4 years), salt pools save money.
Better water feel: dissolved salt gives water a softer feel and less of the sharp chlorine smell associated with high combined chlorine. Skin and eye irritation drops dramatically.
Steadier chemistry: tablet-fed chlorine swings between doses; salt-generated chlorine is steady. Algae blooms drop, weekly maintenance is more predictable, vacation pool care is easier.
Cleanup: no more handling chlorine tablets, no more tablet storage, no more chlorinator maintenance.
Salt is corrosive to some metals and stone over time. Stainless steel ladders, lights, and rails are fine. Decorative aluminum, copper, and untreated natural stone copings degrade faster. Plan to seal natural stone annually and budget for any softer metals being upgraded.
Salt cells need cleaning. Every 3 to 6 months, remove the cell, inspect for calcium scaling on the plates, and soak in a vinegar (mild) or muriatic acid (heavy) solution. Skipping this shortens cell life dramatically.
Salt cells eventually fail. Lifespan: 3 to 7 years. Replacement cost: $400 to $1,200 depending on brand and capacity. Budget this into ownership cost; tablet pools have no equivalent expense.
Cold weather operation: salt cells stop producing chlorine below 60 degrees Fahrenheit water temperature. In winter or shoulder seasons, you may need to supplement with regular chlorine.
Size the generator to your pool volume with 25 percent headroom. A 20,000 gallon pool needs a generator rated for 25,000 to 30,000 gallons. Top brands: Pentair IntelliChlor IC40 (40,000 gallon rating), Hayward AquaRite TurboCell T-15 (40,000 gallon), Jandy TruClear (25,000 to 60,000 gallon variants). Undersized generators run constantly and burn out fast; oversized generators are fine and last longer.
Salt conversion works in any properly built and maintained pool: gunite, fiberglass, vinyl liner. Verify the pool is structurally sound, the liner (if vinyl) is in good condition, decorative stone copings are sealed, and any soft metals have been upgraded. Test current chemistry: pH 7.4 to 7.6, total alkalinity 80 to 120 ppm, calcium hardness 200 to 400 ppm, cyanuric acid 0 to 20 ppm (will raise after conversion to 60 to 80 ppm). Address any out-of-range parameters before conversion.
The cell housing goes in the return plumbing line, after the heater (last component before the return back to the pool). A licensed electrician runs power to the control board (110V or 220V depending on the generator). The control board mounts near the pump on a wall or post within 6 feet of the cell. Cut the return line, glue the cell housing in place with PVC primer and cement (cure 24 hours), wire the power, mount the control board. Most professionals can complete the install in 4 to 8 hours; first-time DIY takes a full weekend.
Target salt concentration: 3,000 to 3,400 ppm depending on generator brand. Calculation: (target ppm - current ppm) x pool gallons / 120,000 = pounds of salt needed. Example: a 20,000-gallon pool at 0 ppm needs (3,200 x 20,000) / 120,000 = 533 pounds of salt, or about 14 forty-pound bags. Buy pool-grade salt (99 percent pure sodium chloride, no anti-caking additives). Generic water-softener salt with no additives also works.
With the pump running, broadcast salt around the perimeter of the pool, away from the skimmer. Salt that goes into the skimmer ends up undissolved against the pump impeller and main drain; broadcast it directly into the pool body. Brush the bottom to dissolve any settled salt. Run the pump 24 to 48 hours for full dissolution. Do not turn on the generator yet.
After 24 to 48 hours of pump runtime, test salt concentration with the generator's built-in display (most read salt level directly) or with a salt test strip or meter. If the reading is at the target 3,000 to 3,400 ppm, you are ready. If below, add the remaining salt; if above, partial drain to dilute. Going slightly under target is safer than going over.
Turn on the salt chlorine generator. Most have a percentage output dial (0 to 100 percent). Start at 50 percent. Run the pump and generator together (the generator only produces chlorine when water is flowing). Monitor free chlorine over the next 3 to 5 days; adjust the percentage up or down to maintain 1 to 3 ppm.
Salt pools need higher cyanuric acid than tablet pools to protect the steady chlorine residual from UV breakdown. Most generator manufacturers specify 60 to 80 ppm. Add stabilizer per the product label; it dissolves slowly through the skimmer over 24 to 48 hours. Re-test after a few days and top off if needed.
The 'right' percentage output depends on pool size, water temperature, sun exposure, swimmer load, and cover use. Start at 50 percent, test free chlorine every 2 to 3 days for the first month, adjust up or down to land at a consistent 1 to 3 ppm. Summer needs higher output, winter much lower (or off if the pool is closed). Keep notes; once you find the right setting for each season, it stays consistent year over year.
Salt conversion is one of the more DIY-friendly pool upgrades. The mechanical work is plumbing and basic electrical; many homeowners with hands-on experience complete the install over a weekend with $1,000 to $2,000 in parts. The chemistry side is straightforward: add salt, balance, run.
Call a pro when you do not have plumbing or electrical experience, when the equipment pad is tight and rerouting is needed, when your pool has older plumbing that needs evaluation before adding the cell, or when you simply want the install warrantied. WETYR Pools provides salt conversion as a standard service with a documented install and one-year follow-up.
WETYR Pools provides full salt water conversion across our installation markets. We size the generator to your pool, source the right brand for your equipment pad, install with proper unions for future cell replacement, wire the control board to code, salt and balance the water, and provide a startup walkthrough. We follow up at 30 and 90 days to confirm the system is dialed in.
Cost for professional salt conversion: $1,500 to $3,500 typical, including the generator hardware, install labor, salt, and chemistry. Pools with complex equipment pads or older plumbing that needs rerouting run $3,000 to $5,000+. Standalone installs (homeowner provides the generator) run $400 to $800 in install labor plus salt and chemistry.
Inspect and clean the salt cell every 3 to 6 months. Look for calcium scaling on the plates; soak in vinegar (mild) or muriatic acid solution (heavy scale) to remove. A scaled cell drops chlorine output and shortens lifespan dramatically.
Keep cyanuric acid in the 60 to 80 ppm range; salt cells work harder when CYA drops, and chlorine breaks down faster in sun. Test salt level monthly during the season and top off as needed. Run the pump enough hours to give the generator runtime; an undersized pump schedule means the generator cannot keep up.
Winterize the cell properly: remove from the housing, clean, store indoors, and cap the housing with the dummy cell. Frozen cells crack; replacement is the most expensive winter failure on a salt pool.

20 of the most-asked questions on Reddit, Quora, and pool owner forums, answered by the WETYR Pools team.
A salt water pool is a chlorine pool where the chlorine is generated on-site from dissolved salt instead of being added as tablets or liquid. Salt concentration is about 3,000 ppm (about a tenth of seawater). A salt chlorine generator at the equipment pad converts the salt to chlorine continuously.
Hardware: $700 to $2,500. Professional install: $400 to $1,200. Salt and chemistry: $100 to $300. Total professional conversion typically $1,500 to $3,500. DIY conversion runs $800 to $2,800 (parts only).
Compared to tablet chlorine cost ($300 to $600 per year), break-even on a $2,500 conversion is 4 to 8 years. Add the cell replacement cost ($400 to $1,200 every 3 to 7 years) and break-even stretches. The math works long-term; the real reason most people convert is water feel and convenience, not cost.
Salt is corrosive to some metals and untreated natural stone over time. Stainless steel ladders, fittings, and lights are fine. Decorative aluminum, copper, soft metals, and unsealed natural stone (especially limestone coping) degrade faster and need annual sealing or replacement with salt-rated material.
Most pools yes: gunite, fiberglass, vinyl liner. The conversion requires a healthy pool with sealed coping, stainless or salt-rated fittings, and a working equipment pad. Pools with heavy aluminum trim, vintage copper plumbing, or unsealed limestone coping should be evaluated first.
Calculate: (3,200 ppm target - current ppm) x pool gallons / 120,000 = pounds of salt. A 20,000-gallon pool starting at 0 ppm needs about 533 pounds (14 forty-pound bags). Use pool-grade salt (99 percent NaCl, no additives) or generic non-iodized water-softener salt without additives.
Lightly. At 3,000 to 3,400 ppm, salt water is noticeable on the lips but not strongly salty. Seawater is about 35,000 ppm (ten times more). The mouthfeel is closer to tears or sweat than to ocean water.
Concrete and well-sealed natural stone hold up. Unsealed stone, especially limestone, etches over time from salt deposits. Travertine pavers should be sealed annually. Wood decking and unsealed brick degrade faster. Stamped concrete with sealant: fine with re-sealing every 2 to 3 years.
3 to 7 years with normal maintenance. The cell lifespan depends on runtime, water chemistry (especially calcium and pH), how often it is cleaned, and the brand. Pentair IntelliChlor IC40 commonly lasts 4 to 6 years. Replacement cells run $400 to $1,200.
Yes, if you have plumbing and basic electrical experience. The install is cutting the return PVC line, gluing the cell housing in, wiring the control board to 110V or 220V power, and mounting the board. Most DIYers complete it over a weekend. Pros do it in 4 to 8 hours.
Top three: Pentair IntelliChlor (premium, best reliability, longer cell life), Hayward AquaRite TurboCell (most common, solid mid-range), Jandy TruClear (good value, integrated with Jandy automation). WETYR Pools installs all three based on the homeowner's existing equipment and preference.
Yes. Salt generators only produce chlorine. You still need to balance pH, total alkalinity, calcium hardness, and cyanuric acid (60 to 80 ppm in salt pools). You still need occasional shocking to break down combined chlorine. Stain and scale preventer, algaecide, and clarifier are sometimes added situationally.
The cell may be dirty (calcium scaling reduces output), the salt level may be low (under 2,700 ppm reduces output), the generator may be set too low for current temperature and demand, or chemistry got out of balance. Shock with regular chlorine, diagnose the cell and chemistry, and increase output if needed. See our How to Fix a Green Pool guide.
Optional. Many homeowners leave the in-line chlorinator in place but empty, as a backup for emergencies or for off-season chlorine if the salt cell stops producing in cold water. Others remove it. Either is fine.
Above-ground specific units exist: Hayward SmartPure, Solaxx Saltron RetroFit, and similar. Smaller capacity, simpler install, often hang on the pool wall rather than plumb in line. Cost: $500 to $1,500.
Yes. WETYR Pools provides salt water conversion as a standard service across our markets. We install Pentair, Hayward, and Jandy systems with a fixed itemized proposal and one-year follow-up. Request through the form on this page or email [email protected].
Generally no; salt pools are standard residential pool equipment from an insurance perspective. Notify your insurer of any equipment upgrade as a routine matter, but expect no change in premium.
Yes after the salt has dissolved and the chlorine generator has reached 1 to 3 ppm chlorine. From the moment salt is added to safe swim usually takes 2 to 4 days. Do not swim during the dissolution or when chlorine is at zero.
Remove the cell from the housing. Inspect the plates for white calcium scaling. Mild scaling: soak the cell upside down in a 1-to-1 vinegar and water solution for 30 minutes. Heavy scaling: soak in a 4-to-1 water to muriatic acid solution for 5 to 15 minutes (acid first into water, never the reverse). Rinse thoroughly, reinstall. Frequency: every 3 to 6 months.
Yes. The water feels softer to the skin (less of the sharp chlorine astringency), the chlorine smell is reduced, and eye irritation drops because combined chlorine builds more slowly. Most people who convert say they would never go back.
