CircuPool SJ55
#12 in Large PoolsFull review
A basic, budget-minded salt system for large pools whose owners want to avoid acid cell cleaning; the short warranty and high salt level are the trade-offs.

3.1/5
A straightforward DIY salt system for pools up to about 45,000 gallons that shows the salt level on its screen; the warranty is shorter than the 7-year headline suggests.

Pros
- Screen shows the salt level in ppm and the water temperature, so you rarely need a separate salt test
- Installing it yourself keeps the warranty, so you can skip the pool-pro install
- Runs on 120 V or 240 V and ships with 1.5 in and 2 in fittings, so it fits most existing pads
Cons
- The 7-year warranty is prorated after year 1: a cell failure in year 3 costs 40% of list
- No Wi-Fi or app, and no named automation system to run it from
- Replacement cells are sold only through CircuPool’s own store
