Hi, I live in The Villages, FL. I am ready to order an iPool, either the Therapy Pool (7' x 7') or the iPool3 (7' x 10'). Both have a maximum water depth of 4'. I plan to put it inside my screen porch, which is about 11'8" x 14"6". I want to use a salt water system, unless there is some better non-chlorine alternative for sanitation for this type of pool. If there are other people in the Central Florida area, I would like any recommendations for installers.
