I've just encountered ICH for the first time so I'm a little frantic of what to do. I have a 25 Gallon (U.S.) it's planted with a lot of fish in it. I have tetras and other types in there...I bought a medication called "Quick Care" which tells me to put 1 drop per 1 gallon in but if i have tetras then 1 drop per 2 gallons...well I was also told that if I put in too little medication, it won't work and if I put too much in it will harm my tetras! Now, what do I do? My sharks are infected...and some of my tetras...I can't put in 1 drop per 1 gallon because of my tetras therefore I'm not putting in enough for my sharks!!!! What do I do?? I've raised the temperature to 26 degress celcius (80 F???) I think!? Going to try raise it to 28! Will raising the temperature help in anyway or just cause more damage? Again, I read or heard all this from somebody....HELP would be most appreciated!!!!
