Although many folks I spoke to (none of whom had first hand experience with Bionizer) told me that Bionizer wouldn't work on pools in Phoenix (US)...I went ahead and fitted the system on my pool in Gilbert in Feb 2015. It has only been three months but this pool is now a whole new ball game compared to the "old pool" I had running and huge amounts of chlorine just to keep it clear. I now never have to test the pH and the copper/silver levels are right on target any time I bother to test which is only about every two weeks.

These guys have really delivered...many weeks now in the 90's (degrees Fahrenheit) and my pool is simply sparkling. I am so glad I didn't listen to the naysayers and went ahead with Bionizer. They have been so helpful...refreshing to be treated special and any question has been fully answered. So glad and so better of now since Bionizer went on my pool.
