Thread: Sand in the bottom of my pool

    Sand in the bottom of my pool

    I vacuum, I backwash. The next morning I have sand or silt on the bottom of the pool again. What do I need to be doing differently?

    Welcome to TFP!!!

    Post up your pool details ... we have no idea what type of filter you have.

    You can put a sock over the returns to see if the "sand" is getting through the filter. If not, then it could just be dust, dirt, pollen that is blown in new everyday.

    Welcome to TFP!

    (Kind of a repeat of what jblizzle said, but some extra info.)

    If you are sure it is sand, rather gritty when you touch it, and not algae, slimy when you touch it, and you have a sand filter then you probably have a damaged lateral inside the sand filter allowing sand to get out of the filter and into the returns. You can confirm that it is a filter problem by attached some panty hose to the return. If sand is trapped in the panty hose then there is certainly some problem with the filter.
