I live in the Dallas/Fort Worth Texas area. This is my third summer to have a pool and I have been using baquacil or Mareva's revatop products. This summer I have had a lot of problem with algae and my pool store told me if I killed the algae and then used optimizer plus or baquacil's Endure (which is just sodium tetraborate and I guess the same thing as the borates this forum is talking about) then I would not have any more problems with algae. Well, I killed it all ( it really was not real bad to begin with, but stubborn) and added $150.00 worth of Optimier plus and my water was great for about a month at which point algae started growing again. borate level stayed above 50 ppm the whole time. So I went through extensive algae killing process again and flocked it to try and get it all out. and added chemicals to the proper levels and optimizer to above 50 ppm again. Well, a week and a half later, green is beginning to grow on the bottom of the pool again. Any suggestions?
Shock stays about 50 ppm
Sanitizer stays between 30 and 50
ph stays at about 7.8
Optimizer stays about 50 ppm or higher
any help would be appreciated.
