    Sandpump Filter question

    Today i was vacuuming the pool and noticed a lot of sand from my sandpump in my pool. Is this normal? I know i had a little last year but this seems a lot. How do i fix that? and why is that happening?

    First, it might not be sand. It could be pollen or very fine silt (if you've recently had rain). One way to test is by brushing. If it fluffs up and disappears it's not sand. OTOH, if it moves along with the brush or feels gritty, then it could very well be sand.

    If it is sand, it could be a broken lateral in the sand filter. A common telltale sign of this would be piles of sand about a foot or so from a return. The sand is so heavy is makes it only a foot or so before falling and piling up on the floor.

    Post a pic if you can - it would definitely help us diagnose.

    Re: Sandpump Filter question

    ok we did get alot of rain so maybe it was that because like you said it disappears when i brush it but i definitely will take a pic when i see it again. Right now my pool is cleaned since i vacuumed it and then put the solar cover on, i just took the cover off and still looks clean but that's also because my pump hasnt been on yet...but once the pump is on i will try to take a pic. Thanks

    Almost surely not sand and very likely dead algae. That indicates a chemistry issue and not filtration.

    Can you post test results?

    If it's dead algae, should he just shock the pool and continue to filter? Or is there any need to shock if the algae is dead?

    Maybe, but test results are really important rather than guess at the condition of OP's pool?
