Well I am doing a fish in cycle. I've don't this with all my freshwater tanks from 29 gallons to 75 and never lost a fish. I've actally only lost one fish and that's because I came home and found him on the floor
Ive been seeing a lot if people dont like this way. But I'm a stay at home dad that babysittes some other kids so I amost never leave the house and an always watch the tank.
I will be getting another 35 pounds or so of live rock later today.
