I'm having a terrible problem getting rid of the algae on the liner. My water is crystal clear, chemicals are balanced....but there is a green "film" on the floor and wall of the liner.
Ive tried brushing several times to filter it out. Ive added pods and cellulose to help my sand filter. I'll back wash and green will wash out of filter. But the green always either settles or grows back to the floors/walls of the liner.
Ive brushed and super shocked, which seems to help for a day or two, then it returns. Ive tried running some extra 3" pucks to the skimmer as well to up the chlorine.
Last night I vacced to waste then brushed, added cellulose and let it filter. Still a little bit cloudy this morning but I'm waiting to see if the green film returns.
We've had a pretty good amount of rain over the last few weeks. No gully washers, rather a steady normal rain. Ive always made sure to shock after a rain. Its been pretty windy and of course Pollen is high.
Is it time for an algaecide?
