Hi - I have a Hayward 4820 DE filter. On the bottom of my pool floor there is a sand-looking substance clumping in a bunch of areas. I believe this is the DE coming back into the pool from my filter. I thoroughly checked the filter for tears and didn't see anything. I added the 6lbs of DE per the instructions on the DE bag so I don't think I'm adding too much (I poured it in very slowly).
Anyone have an idea of what is going wrong? Really appreciate the help!
Thank you,
Brian
