I am having the same issue too. I think it is from the settling of the building and pool and the water robbing the calcium from the structure because it seems to need calcium. I also noticed some bad rust stains in the pebble tec which I am having difficulty getting out. I read the thing about the calcium in earlier strands. I actually put 10 lbs in the last two days and the stains look better and I can see all the way to the bottom of my pool. It is so clean and clear.

what kind of sandpaper can be used underwater? That seems difficult. I have a problem with rust stains in my pebble tec pool.

Hello, I was wondering if anybody else is experiencing a daily ant nightmare in their pool. We have sprayed, placed granules inside and outside of the screened in area, and we still wake up to a million ants, of all kinds in our pool. I don't see a nest anywhere. I live in South Florida.
