This Spring we converted our pool from a salt chlorinator system to a ClearBlue ionizer system, at the recommendation of our pool company's Sales Manager & he was right! The system can be self-installed with basic tools & great instructions or can be installed by a 3rd party. The ionizer unit is very well designed & user friendly. Within a short period of time we had the minerals balanced to recommended levels & other than a small tweak a couple of times, we don't need to touch it! We are really enjoying the reduced chemicals, especially the ability to reduce chlorine levels. We also found a new use for our salt generator box (see photo). We have recommended ClearBlue to other pool owners & 3 are very happy with their ClearBlue units, 1 a salt conversion like ours, 1 a chlorine conversion & a new pool, which was going to be salt. Highly recommended!
