This is one aspect of the BBB method that I am unclear about. I started using the BBB method along with Trichlor in chlorinator about two years ago. One thing I noticed right away was that the bleach seemed to increase my pH if I used it exclusively. This is why I started using it in conjunction with Trichlor. I figured if I balanced the amounts of each I was using I could actually control the pH without the need to add borax or muriatic acid. I have to say that I have not had great luck with the BBB method thus far. I have recently come across this website and the Pool School and have learned a tremendous amount the info I was missing to more completely balance my pool. I feel confident that I will have great success this summer. The most important thing I learned was how to eliminate the constant algae problem I have battled for two years. So, if someone could explain the pH of bleach thing I would greatly appreciate it. If I Google the pH of bleach, I get many results of about 12.5. You would think that this would warrant having to control that when using it in your pool as you primary chlorine source, but I have not seen this addressed on this website or forum yet. Please advise. Thanks.
