Purchased a foreclosed home that came with a pool.
Question about sand filter. Put it on filter mode and turned on the pump and sand came out the pool return. I quickly grabbed my leaf net and put over one of the returns (there are two total that I see) and gathered about 2 cups of sand before it starter flowing clear. As it appeared to be losing pressure (maybe 10 minutes), I switched back to recirc, and when I fired up the pump I got another 2-3 cups sand caught. I probably missed 8 or so cups that deposited into the pool. Does this signify a need for replacement or something else I can do (clean/replace sand) to fix this?
Also used a pool vacuum and scooped up much sand under the other return.
