Give it to me straight. It's brown and puffs away when you touch it. It forms a perfect little ring all the way around our round pool. I won't have any in the morning and it will be there in the afternoon. I did go from swamp thing to swimming pool, but I tested my water last night and had FC7 no CC. Tested again this morning and had FC6 no CC.
Husband says it is dead algae...I want to make sure. I know that something blows into my pool after we turn on the pump through the returns....but this much?
