I've had problems with my pool being cloudy the last week or so.
Current test results
I hadn't used the pool over the weekend, and hadn't vacuumed in a week. There was a lot of dirt on the floor of pool. I vacuumed it up yesterday, and also noticed low pressure coming out of the return. I took cartridge out and sprayed it with the hose, but used no cleaning agent since I had none. I figured spraying it was better than nothing. There was a LOT of yellow and crud/scum on the cartridge, which I'm assuming is dirt and pollen. Put it back white, and the return was pushing out strong as ever.
However, the PSI on my pressure gauge did not drop. It was 15 before cleaning, and not 15 after. Odd, especially considering the return is pushing out a lot more water.
So now my pool is blue, but cloudy. Not greenish, or whitish, but just a cloudy blue. I can see the bottom, but it is hazy. I did an overnight chlorine loss test monday and tuesday, and am not losing chlorine over night. Have been running pump constantly since cleaning last night, but i'm still cloudy.
