Happy Spring everybody, I am a happy pool owner in SC with a 20,000 gal round AG pool. I started using the BBB method last year after a friend told me about the Pool Solutions website, but just joining the forum now. I wanted to ask about recommendations on an automatic chlorine feeder, if people use them successfully. Do you guys use them with the trichlor pucks?

We also just replaced our liner and so I'll be adding BBB when it's done filling up. Should I add CYA before I put in BBB since the CYA will lower the pH? It takes forever to dissolve. I put it in a sock last year and hung it with a bungee near the return, but it was after I put in BBB, and I had to readjust.

Last question, what is the best way to clean a sand filter (are the cleaners a scam?) and how often should it be changed? Is it a pain?
