    Sand Filter issues

    Okay, we had an issue filtering the water. All numbers were in the acceptable range but pool was cloudy. Added DE to filter. Pool got crystal clear minus some sand,dirt, debris on the bottom. Now we have vaccumed the pool and it seems the filter is just spitting it back into the pool. It is a very fine sand almost dust.
    Should I use a clarifier to clump it out and catch it?
    Until I can take apart the filter and service the sand check for lateral damage?

    Re: Sand Filter issues

    Have you backwashed the DE out of the filter yet? Have you added new sand to the filter recently? You can check the laterals for damage. I would drain the filter of water and let it dry for a while, then you can more easily vacuum (shop vac) out the sand and inspect the laterals. You can reuse the same sand.

    Clarifiers won't help you long term (or even short term) if your filter is spewing dust.
