I am currently treating my 55 gallon tank for ich. I took out the filter pads since the directions on the meds said to remove charcoal from the tank. In all, I took out four. I didn't want to lose the bacteria living on them, so I put them in very shallow water (only halfway covers them) and have been putting a little fish food in thinking maybe it will give the bacteria something to feed off of as it decomposes. Is this going to work, or am I just wasting my time?
