First spring with our new pool and we are encountering a recurring problem with what appears to be dirt on our tanning ledge, steps and benches. We brush it daily and it returns. We did notice it during the fall but it wasn’t as prevalent. The pool builder said to keep brushing and the sand filter would pick it up but it’s not happening. We have not vacuumed yet since he told us it would be filtered out. If we brush it, it makes the water cloudy. We have also noticed there appears to be more when we add chemicals or increase the percentage on the SWG. Any advice would be appreciated. We are working on getting the pool ready for the summer and this is a constant nuisance. I realize this is all a learning process.
