Your saltwater pool can look perfect on the surface while the sanitizer quietly drops to zero, and when that happens most people blame the salt level. I go straight to the real weak link: the salt chlorine generator cell. After 35 years in the pool industry, I’ve seen the same failure patterns repeat, from undersized cells that can’t keep up in summer to perfectly sized systems that still lose the fight because the pump isn’t running long enough.

We unpack why salt cells are expensive (titanium plates coated with ruthenium or iridium), why “bigger cell = longer life” isn’t as guaranteed as it used to be, and why I still prefer a higher gallon-rated cell for practical chlorine production headroom. 

From there, it’s the stuff that actually trips up saltwater pool maintenance: cyanuric acid targets (including why many pros like about 80 ppm CYA for salt pools), phosphates and algae burning through chlorine, calcium scale blocking conductivity, and the cleaning mistakes that strip coatings and shorten cell life. We also cover cell lifespan (often about 10,000 hours), how to check remaining life, why a dying cell can throw false low-salt readings, and why adding more salt can create an even bigger problem. 

• why I still like an oversized salt cell for production headroom
• chlorine output benchmarks for common Pentair IC and Hayward T-Cell models
• how pump runtime and output percentage control real-world chlorine production
• why algae, cloudiness, phosphates, and low CYA can overwhelm a salt system
• why many pros target about 80 ppm cyanuric acid for saltwater pools
• calcium buildup on plates and how it blocks conductivity
• Hayward AquaRite 90-day inspect cell reminder and how it can mislead
• safe salt cell cleaning and how too much muriatic acid ruins coatings
• typical salt cell lifespan in hours and what that means in years
• signs a cell is dying including false low salt readings
• why adding salt does not fix a dying cell and can oversalt the pool
• white flake blowback vs mushy flakes and what to try for each
• coo
