Below are my most recent results of water testing from the pool center. I was told to add some more acid to lower the pH, my salt levels were good but my chlorine was low, so maybe I'd need to clean the SWG?? My water looks clear, but the bottom seems to have yellowish/brownish settlement almost like dots? Any suggestions?? They vac up but they are stubborn in some areas.
