Hi Everyone --
Thanks for the great replies! I'm now at a few weeks in trying to get this water cleared-up, and though it's MUCH clearer then it was, it's still cloudy as heck. I can at least see the bottom alittle (sometimes). I've been working with the guys at Leslie Pools and I've used about three different products. They think there's probably some leaves or something at the bottom I'm missing with the vacuum and algae or something is growing under it and releasing more crap into the pool.
I'm currently draining about 1/4 to 1/2 the water to refill, and hopefully that'll give me a good starting point where I can see the bottom and vacuum up whatever the heck is down there. I've actually gotten in it a few times and walked around, though I couldn't see the bottom.
The pool does have a sand filter, and the sand was just changed out two years ago -- so I assume it's still okay.
But I'll post another message in the next few days after I've filled it back up and ran more chlorine through it.
Thanks for all the input though... it's encouraging to know that it'll be clean at some point -- even though we've already missed out on most of the summer thus far :-/
Take care --
Alex
