cloudy water. Please help!

[dhale63]

First off let me say thanks for your help on other pool issues. You guys are great! My new problem is that our 30' AG (20000 gal) pool has turned a little cloudy. I can see the bottom and can easily see the pattern on the liner but it is definately not as clear as it was three weeks ago. It's not a huge issue yet but I don't want it to get any worse. My numbers are as follows:

fc 6.5
cc 0
tc 6.5
ph 7.6
cal 120
alk 240
cya 30
temp 75

We have a pretty heavy swimmer load. 4 kids and 1 or two adults swim at least 2 or 3 times per day. I know my alk is high. Could this be part of the problem. It is filled with well water (no choice) but there aren't any metal issues, just alk issues. Any help would be appreciated.
Thanks,
Dave

I would up your filter run time as a first try at solving it. Run it for 2 or 3 days and see if it helps, maybe brushing or vacuuming during the run too to get things stirred up.

Shock it, and leave your filter running.

Thanks for the advice. I will do all those things and see how it progresses.
