I have a 60g tank with artificial reef, canopy lights, HOB filter, used live sand to cycle, temp stays about 76. Its been cycling for about 5 weeks and the numbers I believe to be optimal: PH=8.3, Ammonia, Nitrites and Nitrates = 0. I set up a 10g QT with the bare minimum (small HOB filter, power head, heater, light and couple of hiding places for new fish. Just purchased couple of clown fish yesterday to get me started. They've been acclimated and seem to be doing fine. Problem is that this morning as I was looking at my display tank where the damsels are, I noticed some white spots on 2 out of the three of them. The one has couple of spots on its tail and some more on its top fin. The other one has couple of spots on its tail. I fear that it could be ich. Tried to get them out the tank for over an hour, figured they would eventually get tired, but I got frustrated. My LFS sold me this "Kick-Ich" stuff and advised me on how to use it. Would it be a good idea to pour it in the main tank since I still have to watch my two clown fish for a few weeks in my QT. He says the stuff is invertebrates ready and it should run its course in about 15 days which is not as long as I will keep the new fish in QT.
