OKAY... I am currently cycling my 40gal aquarium. I had 10 feeder goldish in there, and they got ich. I tried treating them with salt, and brought the temp up a bit. At the same time my ammonia spiked and i lost 3 fish-they all seemed pretty sick. SO...I went to work today, and my cute (but not so bright) significant other went to the pet store and talked to someone about this. There advice: Get rid of the feeders, get some new fish to cycle the tank with, and add some blue ich chemicals to kill the ich in the tank--continue the cycle and get my new fish... I got home today, and no more feeders, and I have some danios in my tank. Hubby didnt put the blue stuff in the water yet--i wont let him till i know we are going about this right. ALSO, the ammonia levels are starting to drop (around 1.0 now, from abiut 3.0). So do i use the blue stuff and leave my tank for a week or so--untill ammonia levels have been 0 for a while or what??? Will the ich medication kill all my "good" bacteria?? Also i have some water ready to do about a 20% change tomarrow...
