AquaTrol above ground pool
AquaTrol low salt chlorine generator for above ground pools by Hayward
Just a little salt and long hours of pleasuring. Using advanced technology, the AquaTrol chlorinator can effectively sanitize your pool water with as little as one teaspoon of salt per gallon of water. Once you have introduced salt into your pool, you will rarely have to add more. The easy-to-access operator station displays all AquaTrol data, including operating status and salt concentration.
