well, alot of people suggest raising the temp to 82 or higher and adding salt...but its questionable how much, some say 1 tsp per gallon, some say 1 tsp per 5 gallons...i dunno. but there are ALOT of ich(ick) medications on the market out there. just make sure whatever you do that you follow through with the medication for about 14 days. ick has several stages, and the only time that the ick will respond to medication is during the "free-swimming" stage...so the only way to make sure you've killed it all is to medicate for 2 weeks. you can buy ick medicine at your lfs. products such as "tank buddies" fizz tabs and such might not be the best since they suggest treating your tank only once, but then again, some say that brand works great. i think it becomes trial and error as far as which products work most efficiently, but again i would go for the one that says to treat for 10-14 days....anyways. someone a little more experienced might have some more info, but this is what i know. good luck!
