    Incorrect sand in filter?

    I inherited my pool with the house six seasons ago. I had a new liner installed, but otherwise have followed TFP guidance and have had very little trouble with it. I've been noticing that my filter doesn't seem to filter correctly. It's a Hayward sand filter, and I recently noticed while...

    So glad for TFP

    I bought a home over 2 years ago with an in-ground pool that was in desperate need of a liner. While I was getting that worked out I ran across the TFP method. As an engineer and chronic DIY-type, it fit my philosophy perfectly. I've had very little trouble maintaining a beautiful pool and this...

    Pool light cable too short

    My pool light is burned out, but the cable is too short to get it above the water line. Any ideas on how to replace it without dropping 18" of water?

    CYA Going Down

    This is my first year having a pool, and TFP has been a great resource. I initially set my CYA around 50 (in May). Now it is about 30. I have not worried about it too much, but why am I losing that much? I don't think splash-out explains it, because (according to the calculator) I'd have to lose...

    Not sure if I have algae

    First off, a huge thanks to this site and participants because this is the first question I've needed to ask. I'm a new pool owner (bought a house with one this spring), but I've been following the TFP methodology and found it to be simple. We had a new liner installed in May.I never SLAMed the...
