    CYA Next to Non-Existent

    Hi folks. I am a little baffled here as this has NEVER been an issue with my pool before, but my CYA levels are WELL below the minimum levels. I live on Long Island, NY here in the northeast, which had a pretty wet late winter and most of the spring, so perhaps the large amount of water that...

    New Hayward DE4820 Leaking at Clamp

    I had to purchase a new Hayward DE4820 filter thanks to my old one finally cracking over this past winter. I have been running it for a couple of days and did not notice or see any leakage, but now that I finally got to clean and SLAM my pool, I have noticed a very small bit of leakage at the...

    Water Temps vs. Running Pump until October

    Hi all. I have read the awesome primer on how to close your in-ground pool, and although I have been closing mine for 13 years now, I am debating following the advice and waiting until the water is "solidly below 60 degrees." I have a mesh LoopLoc for an 18 x 36 vinyl pool. However, that does...

    Recurrent Algae and High Phosphate Levels

    Hello all- I know this topic has been beaten to death, but I thought I'd try to pick some brains in a fresh thread. My pool, which is usually not prone to algae bloom, and chemically balanced pretty darn well according to my own tests and that of two separate local pool stores, has been...
