milky looking cloudy water

[Terry.G]

had my water tested brought all chem levels within range water still cloudy tried shock & clarafier when I turn my filter off for a few days water gets clear but leaves a powdery substance on bottom when I try to vacum the dusty stuff stirs up and the pool is cloudy again.it's an above ground pool & it uses a cartridge filter which I did change.Please Help

is this a regular above ground or a blow up type above ground? Can you vaccum to waste with your filter? If so do that, you will have to fill it back up and you will have to do it several times but it will eventually clear up. Also I have found that sunlight is your cloudy water's best friend if you have your chems all right... mine was cloudy, I used a super floc, vaccumed to waste a couple times, then let the sun clear it up, it's great now!!

I've had that same problem and spent half of my summer fighting with it. I believe it was dead algae that settled to the bottom of the pool after it was killed by a shock treatment. It's such a fine substance (like powder) that it cycles through the filter system and right back into the pool.

Trun off the pump and let the water settle.
Push all the dead algae to one corner of the pool and let the water settle.
Vacuum all the dead algae on waste to remove it from the pool and prevent it from entering back into the filter.

You might have to do this more then once - until all dead algae is clear from the pool and filter system.
