Well said! Perhaps you might want to consider putting this info into a FAQ and 'sticking' it in the forum. It is info anyone putting in a pool or spa should have. Ozone seems to be getting a hard sell these days. I had 2 different builders include ozone systems in their quotes when I was first shopping for my pool/spa a few years back! If I had not had personal experience in using ozone in fish tanks I might have made a mistake and put one in becasue they DO look good on paper!
