Been dealing with dust/debris at the bottom of my pool for a few years now. Last spring had a new liner put in and a week later bam there it is again. The dust/debris collects in the crevices at the bottom of the pool. When I vacuum it, it poofs into a cloud then eventually settles again after I think I got it all cleaned out. I have a cartridge filter so I cannot "vacuum to waste" or backwash. I have tried flock(which only made a huge mess in my pool) and also clarifier. I've taken the cartridge out and hosed it off. Tried using a skimmer sock and even put a little DE powder in the skimmer sock. This is a never ending battle. It's like shoveling while it's still snowing. The other day i put 3 jugs of pool shock in so my chlorine is very high right now. Can anyone take a guess as to what I am dealing with here? I don't know how to get rid of it. I vacuum twice a day every day and it just keeps coming back within a few hours. I will attach a pic. it is all over the bottom of my 24' round above ground pool.
