My pool needs to be brushed every three days to get rid of a light coating of algae dust on the pool floor and walls. My latest chem readings are Temp 85, fc 6, ph 7.5,TA 80, cya 60, Salt 3500. The new swg is set to maintain my FC at 6, and I am running the filter on low speed for 12 hrs a day. Lots of sun lately. I passed OCLT last week with little loss of chlorine. Any suggestions on the prevention of this algae constantly re-appearing? Otherwise, the water is clear.
Thanks
