Well I am not sure what you meen buy"the new rocks have nothing on them"...It would be best in my opinion to cook the rocks in dark ttubs with a weekly dunk and swish and water change but certainly you dont have to do that if you dont want to.If you have cured rocks then they can go into the system rite away that is correct.I thought you still had to cure the rocks.Basic curing usualy takes about three weeks though.
