My pool went green again. It's my fault. I wasn't testing appropriately and then there was a bad storm and it got tons of debris and I woke up to green. I'm mid slam right now(hahaha), but I'm pretty confident my filter media has about had it. I know I can add DE to help it out, but idk when this sand was replaced and id like to do it and know it's working. My question is this : is there anything wrong with the quickrete sand filter materiel from Home Depot at 5 and a half bucks for 50 pounds? Quikrete 50 lb.
