Simple and Clear

Easy to assemble and hook up, directions were simple yet not too vague. Installed on a 5500gal above ground saltwater pool. Works like charm! My water is always crystal clear. Definitely recommend, even for folks like me that have no clue what they are doing.

Saltwater generator

This is by far the best purchase I have made for the pool. Soft water no harsh chemicals. It operates like a dream. Would buy it again and again. The last smaller model I had for more than 10 years . Well built products.
