Help, im at a loss. 5 fish dead in less than 1 week

JWS, thanks for your reply.

Makes sense, but I am one to find out the source of the problem not second guess. If my system was unable to handle the load, and fish produce waste as ammonia, and it was not able to break down, I should be measuring good amounts of ammonia, nitrite, let alone trace amounts.

The fact that two more chromis are missing and decomposing somewhere should send my ammonia through the roof, and ive been testing 2-3 X /day for the past few days, and still nothing.

The live rock came from a heavily stocked tank, and I would think that there is a healthy population of bacteria breaking down this ammonia.

Yes going slow is my next step, but I still would like to know WHY they died.
