I am glad that Baquacil works for you. I used it for a year with no problems.
I opened the pool this year with no problems. Then I developed an algae problem, then water mold, and then cloudy water that would not clear up.
I checked all of my levels as I was supposed to, had 2 cartridge filters, that I changed out monthly, brushed the pool every week, etc. etc. and still had problems.
I am new to the BBB method (2 weeks now), but I spend MUCH less time on the pool than I did with Baquacil. I check my ph and chlorine levels each evening, other levels once a week. Put the pool cleaner in as needed and the water has never been so clear. Someone came over this past Sunday and said "oh your pool just sparkles".....the first time I've ever heard that comment about my pool!
