The following should be done after you are sure the filter is working properlyI went out tonight about 10:00 pm and could see stuff settled on the bottom, so swept the entire pool again
If you can see stuff that has settled on the bottom, vacuum it up ! Don't sweep it back into suspension. And when you are done vacumming, leave the vacuum facing upward at the bottom of the pool. This will draw the dirtier water from the bottom through the hose instead of just the cleaner water from the top through the skimmer. Unused pools tend to filter the top water more (no bathers to mix it up). You were also aerating, which decreases mixing even more.
I also think that if the water isn't mixing well, there is a chance the algae at the bottom isn't getting high enough doses of CL to be killed.
I am suggesting this as I have seen no mention of the pool having a bottom drain.
