I have a 15,000 gallon in-ground concrete pool. The surface of the pool has pretty much worn off (rough on the feet). Every time I try and brush the pool, I kick up clouds of something, not sure if it's organic or more of the pool surface. Then it takes a couple days for the cloudiness to go away. I seem to always be battling slight cloudiness anyway, and a visible layer of greenish silt tends to build up on the bottom of the pool 3-4 days after vacuuming.
Should I still be brushing given the eroded surface of the pool?
