We just got home from a short vacation. Our tank's temperature had dropped from a steady 79 degrees down to about 70 degrees and out black molly had tiny white raised spots all over. I think this is ICH. We have a planted 10 gallon tank with a pair of guppies, the molly, a betta, a snail, and a cory and a few neon tetras, which all look fine, although one of the tetras looks a little "faded." The water looks slightly cloudy, too. I've raised the temperture. Can all of these fish take the higher temperature needed to kill ICH? Ammonia is at 0, Nitrites at 0, Nitrates at 40 ppm. ph at 7.4
We also have a newly planted empty 10 gal tank which I was going to start with fishless cycling after we got back from vacation, and transfer some of the fish into. It's been running for a week now with no fish, so everything is at zero. Should I move the molly into this tank? I also have an empty 10 gal and a cheap filter I could use to set up an emergency hospital tank. I've read that salt will kill ICH and also that mollies don't mind a bit of salt. What's my bast plan of action. If at all possible, I'd rather avoid having to use chemicals in my first tank that would mean I'd have to start from scratch with cycling.

. do a big water change and add some salt (not sure how much but the packaging usually says, make sure that there are no scaless fish in the treated tank and watch your mollies get better
