we just got an above ground pool installed and were sold the permasalt system. we were told it was easier to maintain the water quality. well we're having problems. there is algae on the sides and bottom of pool (slimy stuff). I checked the levels and we have low chlorine (obviously), high alkalinity, high PH, low stabilizer. if we were using chlorine we would just throw some chlorine pucks in but since we're not, what do we do to get the levels where they are supposed to be?
