I have a 29 gallon tropical freshwater tank. I have some rocks(from fish store), fake plants and live ones. I have a bubbler as well. The fish I have are electric yellow cichlid, dimissioni, electric blue johanna and another one but I don't know its name. My ammonia levels have been reading toxic since 6/13/11 which is a few days after I set it up. I have tried ammonia neutralizers but it hasn't changed. I cannot figure this out! I have done 2 water changes since then(one just yesterday) I always condition the water before putting it in the tank. This is driving me crazy!
