I have what i believe to be a very nice 30 gal planted tank that has been up for nearly 4 years now and have had not a single problem with disease until now. I have lost 3 fish in the last 2 days due to ich. I have been using the "Ick Clear" product, but it does not seem to be helping much - if at all. I have raised the water temp to 80-82, lowered the water level to increase the oxygen level and have been religious about a daily 25% water change before the next treatment goes in. Am I jumping the gun, or do I need to be doing something else?? Please help!
