I am not aware of having any algae. My pool has always been crystal clear until this stuff started settling out a couple of weeks ago. After vacuuming last night, the stuff had settled back out again this morning.

Thanks for the advice BigDave. I had been wondering how to rig a makeshift filter onto my vaccum. I saw another thread where somebody used the stuffing out of a pillow, a bucket and a sump pump to filter iron out of their pool. Whether this is iron, algae or whatever, I need a makeshift filter to hook to my vaccum that will catch this "gunk" and not allow it to disperse back into my pool. I think the particles may be too small for even a nylon stocking. They seem to dissapear when you disturb them or try to touch them.
