The pool lost about 10 FC last night. (Started at 30 and this morning it was at 20) CC is at 2. The color of the water has changed from a dark swampy green to a light teal color. I am not able to see the bottom at all.

Does this sound ok that I am losing this much Chlorine at night? My pump and filter has been running constantly and everytime I sweep the sides and bottom I stir up more algae. Should I go ahead and try to vacuum even though I cant see anything yet, or just keep doing what I have been?

Thanks

Tim
