Pentair IntelliChlor IC20
#10 in In-GroundFull review
Pentair’s small IntelliChlor for pools up to 20,000 gallons, back in the US; the newer LT25 fits the same power center and shows salt in ppm.
The Pentair IntelliChlor IC20 rates 2.9 among in-ground salt chlorinators; the Solaxx Saltron Retro rates 2.4 among above-ground ones.
Solaxx Saltron Retro
#7 in Above-GroundFull review
For above-ground pools up to 20,000 gallons whose owners want a salt system without cutting into the pump hoses; the short warranty is the catch.

| Warranty terms | Pentair's US relaunch page gives the reintroduced IC20/IC40/IC60 a 3-year warranty when bought through a pool professional. Pentair's warranty page gives TradeGrade products bought online a much shorter limited warranty (60 days on the product page; 1 year, parts only, on the warranty page). | 1-year warranty (product page and brochure). The manual voids it for acid-cleaning damage, a power supply not mounted vertically, or a cell left in freezing water. |
