    Winter shock

    It's my second year closing and I'm trying to plan since I'll be closing in the next week or so. Last year there was some winter shock left behind by the previous owners so I threw it in and now I'm trying to figure out if I should again. What is winter shock for and should I put some in while...

    Hayward EC50 Leaking DE into Pool when Pump is First Turned On

    I am having an issue with my EC50 above-ground pool filter. It seems to have a leak somewhere but I don't see anything obvious. What is happening is that when I first turn the pump on, the water return will shoot DE back into the pool for about 5-10 seconds, maybe a little longer. I'm guessing...
