About a week and a half ago, I noticed some streaks of this brown dust on the bottom of my pool. I did an attempt to vaccume it but my pump is a pretty sucky 2500g/hr pump and the dirt dispersed into the water before it could get sucked up. 2 days later I go to check up on it and now it pretty much look as you see here (It hasn't gotten any better or worse over the course of the week).

This stuff is annoying, it dosn't stick to anything and just settles to the bottom. for most of the week now I have left the vaccume hooked up so the intake source would be the bottom of the pool in hopes of nabbing this stuff as it settles, but it dosn't seem to be working. I've gone ahead and run the vacuum around stirring it all up into a cloudy mess to help with breaking it down as well as lift it from the floor, but nothing seems to work well. The chlorine levels in the pool are normal (its a small pool so pretty much any application will easily bring it to 2-4ppm). I've shocked it twice, the second being yesterday, but it dosn't seem to want to break down. It is really annoying stuff.
Here is some more pictures;
Here you can see the "bands" of dirt, showing that it is loose and just moves with the water action.
Unfortunately I had stired up the stuff to much and it was no longer sitting ontop of my hoses for a close up, but I got this from a pocket of my cover that has been hanging on the side of the pool all this time.
Anyone know what this is? Chlorine dosn't seem to be breaking it down at all, and I am not entirely sure if my filter filters it all as well. I have pulled it twice and washed out a bit of dirt that was concentrated around the nozzle area, but the large percentage of the filters area was still white, leading me to belive that alot of this is passing through it. Pretty much my next step is to run the vacuum hose (or detach the outlet hose) out of the pool and see how much dirt I can grab from the bottom and drain from the pool.
My geographic location is the eastern shore of fl if that helps any. I have some big trees near the pool but none are over it. Chlorine levels are usually kept between 2-5 ppm (not OTO), no idea how high they get when I am shocking. ph is 7.5. PH is very good at staying still. The pool is 1700 gallons.
