My Fishtank of Death - Part II

Please see previous post: http://tinyurl.com/9h9ga

OK, here is what I have done since I got many helpful responses. I got a
power head for the UGF and have been changing/vacuming
once a week. I also reduced the # hours that my tank light is on. I also
got a larger air stone. My tank is still
completely clouded for several weeks now. The remaining fish seem to be OK.
It is so mukry, that I can't even see if my
remaining frog is alive. I have been testing the water, and every thing
seems to be in tolerance. I then took a water sample to a local pet store
that has a good fish dept. They said my pH was low (my test kit registered
normal - 6.8-7.1). He said to turn the heat up to 78-80 deg. and see what
happens. I did that, and no changes yet. I have tried the algae removers
and clearing solutions, and no changes.
Any more suggestions?

Thanks.
