I have ick in my tank and all of my fish are almost dead. I got some stuff to try to help it. I have a small tank that I sent up and put some fish in there. I read that if you bring the temp up to 85 it will kill it off. Does this mean I have to drain my whole entire tank out andboil my live rock to I need help on what to do.with a.230 gallon tank. I have snails and star fish in there.
