I slammed my pool 2 weeks back, chlorine levels were stable for a week, we had small rainfall 3 days back, now again I have high chlorine demand, spending too much money in chemicals . Only thing I suspect is black spots around the pool light fixtures, I don't know how to unscrew and clean those, never done that before. I backwashed my pool 2 weeks back during the slamming process, today I noticed there is a 7 psi increase.
