I am running an intex 12 in sand filter on a 12x30 prism pool. I recently started to get a lot of silt on bottom of pool. I’m wondering if it’s too much power and it is either over circulating and not filtering properly. It has not always been an issue but started to get progressively worse. I thought was mustard algae and it is not. I replaced sand and it still Happened, I ran a test and out the old weak filter in that came with pool And no silt On bottom. Getting very frustrated with what is causing it! Any insight welcome.
