I had just gotten the water crystal clear from a green state before vacation. We were gone for 12 days so I put on the solar blanket, we do not have a full cover. When we got home there was a fair amount of tree stuff and pine needles that slip along the side. It was cloudy again and now green, not as bad as before so I am slamming again (getting used to this). I am going to clean the solar blanket this weekend too before thinking about putting it back on, maybe it has something on it causing the algae. My question is with the new Epoxy paint, done in July, can the high FC levels affect the paint/plaster? How much affect does Ph have on the paint/plaster too?
