I have had the tank up for about a week and added a shrimp in the tank day one. I added over 100 lbs of liverock from an existing system, livesand, 2 bottles of bio spira (150 gallon rating worth), and a 12x12 sponge from my system that has been running for a year. I have had 0 trace of ammonia and even threw a cheap zoa in to see what happens. The shrimp is completely rotted and smells horrible. Is it possible that my tank skipped the cycle due to the mature liverock and all the extra bacteria I added?
