i got a 26 gallon aquarium with 30lbs of LR and its been cycling for about 6 weeks now. All tests for ammonia and nitrite and nitrate are 0 now yet i have lost a royal gramma, false perc, fire goby, and a green chromis. The guy at the LFS store its a ammonia spike but i dont think so. its making me really ticked off not know whats killing my fish. I got a azure damselfish and a six line wrasse some corals, inverts, crabs, in the tank right now and there doing fine except it seems the damsel has ick. what should i do guys and gals??
