Our pool started to get randomly cloudy a week or so ago. I checked everything and the water was balanced had plenty of chlorine then vacuumed and shocked it. The next couple days it kept getting worse which I then noticed that the pump had some air and now I've been having to bleed the filter several times a day so clearly ots not filtering the water at full capacity. The pool is about to turn green now. I've replaced the o ring on the filter housing and checked the o ring on pump. no cracks or leaks that we can notice. I'm all.oit of troubleshooting and the place we bought the pool , they are not helpful. the pump and cartridge filter is hayward , it's an aboveground 24ft. it's all only 5 years old. This is my last stop before calling a professional to look at it.
