I'm with Dave, and wouldn't advise the "high PH" and Dave is right as well about the 7.2 PH being fine, but I really like to keep mine a little on the high side (7.5 - 7.8), I'm kind of "walking the line" if you know what I mean. I do however test darn near every day and twice if it rains. It could very well be my imagination but 7.5 seams to feel a lot different than 7.2 on the eyes. I also have 3200 ppm of salt in a non SWC pool, all for eye comfort.
