I obtained some dead live rock from a friend. I knew about the dying bacteria that may cause an ammonia spike in my tank if i put it in, which is why i decided to cure it. I put it in a bucket of salt water with a power head where it has been sitting for a week now. I measured the parameters and the ammonia level is .5 ppm and nitrates and nitrites are at 0. This sort of makes sense to me but isnt it supposed to be broken down to nitrites then nitrates? anyway im wondering about next steps ? When can i put it in the Display tank? Should i change the water out put new saltwater with next to no ammonia then let the ammonia levels rise one more time before i throw the rocks in the DT?
