Had to SLAM this week after what I thought was an annoying dirt/pollen turned out to be algae after OCLT. I find myself here every spring. I live on the gulf coast with very mild Winters and wacky spring (30 one day, 80 the next). My question to fellow warm weather owners - when do you start maintaining chlorine levels & running your pump longer in order to avoid having to SLAM? Or do you just maintain all winter long? I'm guessing I need to start getting the pool in shape as early as Jan since this algae showed up in early Feb (we had warmest Feb on record this year). I'm getting too old for this! Never had this problem with my old saltwater pool. Thinking about converting this to saltwater when it comes time to drain & change the liner.
