Hello and welcome!! I see you did another post about your CYA issue. Chances are you'll have to exchange some water. Please visit Pool School - Trouble Free Pool and read up on the articles. If you're like me you'll have to read them several times before it kicks in. A specific test kit is recommended - the goal is for you to be self-sufficient and not dependent on the Pool $tore. You'll get more bang for your buck with TFTestkits.net and I highly recommend the SpeedStir. You won't regret following the guidelines on this forum. Happy swimming!
