When I last upgraded from a 55 to a 75 (due to leaker), I just transferred everything with no problems. My new 125 has 100# of cured LR. About a week after the start up I added another 30# that was cured but shipped wet for a 2 day transit. (it smelled fine) I also added a couple scoops of sand from my old tank and 2 pieces of raw scallops. It is now 3 weeks later and I am still reading no ammonia, NO2 or NO3. Is it just not enough time yet or is there a possibility that it may not go thru a cycle? When I switch tanks, I will be adding about 60# more of rock from established tank.
thanks
