What is the brown stuff that builds up if you don't brush and vacuum? If I run my had across the bottom where I see it, it goes away like a fine powder. It isn't algea is it? My chlorine is fine and the water is clear.

I know my pool chemistry is perfect, and I can still raise a cloud of dust with the Wall Whale, especially if it's been windy. If your windowsills, patio table, etc. have dust on them, so does the pool. 'cept it sinks in the pool and likes to cling to the walls for some reason.
