Greetings, so far I've been performing a in fish cycle going on week 3, on a 45 gallon tank. I've 50% PWC with PRIME doses everyday. Just trying to get rid of the Ammonia and Nitrite levels, so far good. Ammonia is at 0 ppm and Nitrite is at .25 ppm. My water temp is stable at 78 degree and I check the temp of the new water for my PWC. I introduced 2 x-ray tetras last week, then 2 red eye tetras last night. Today I notice a spot of Ick on one of my red eye tetras. How should I go about treating Ick? I've stayed away from water conditioners, bacteria additives. The only thing I've treated my water is with PRIME. Any help, direction and advice will be appreciated Thanks
