i'm new to this forum. need help with what chemicals to use as my regular maintenance. have inground pool with vinyl liner. as a new pool owner was told by the installer to use bioguard products(i know selling their products but that's what i used....burn out, stingy sticks, back up alagecide. last year, i used the same except didn't use stingy sticks, used 3" tablets in the skimmer from walmart. friend told me to use bleach instead of the burn out but to continue to use the 3" tablets in the skimmer and back up alagecide.....can you help me and tell me what you find is best to use as the regular maintenance program...what to use, how often to use, and if you recommend bleach, how much to use and how often. thank you.
