I agree wif Wei n Tanzy - IMO, since the tank is new, i tink adding the cured/uncured LR is good since the die-off from the rock will start off the cycle. besides, its a little inconvenient to get a few pails to put the smelly LR to 'cure' them... in addition, more LR shld help speed up the cycling process...
a small shrimp may not be enuff to start the cycle too.
just mi 2 cents
