Hey guys, I've been a long time lurker but I finally have a question that I don't think has been asked so I'm taking the plunge to throw my hat into the reef2reef community. So first off, thanks for all the info you've already unknowingly given me!! I'm not a total newbe... I've kept a 30 gal reef tank for about 18 months. I've recently decided to upgrade to a 90 gal tank and I've been cycling for just over three weeks now. I have recently started the Red Sea mature reef starter kit and i'm through the initial ammonia spike. I have about 50 lbs of dry rock curing in the tank. I would like to start to add my live rock from my old 30 gal (I have about 30lbs of rock in there) in order to help seed the new tank with the denitrifying bacteria. The old tank is still running but I will break down once transfer is completed. Here's my question (sorry for being long winded): With probably another 2 weeks remaining on my cycle, how much rock can I pillage from my 30gal without harming the fish still living in there? I have 2 clowns, 1 bangai Cardinal, 1 starry Blenny, 1 file fish and 1 neon Goby. I also have minimal coral; red mushrooms and green star polyp, which i wouldn't move until cycle is complete. Could these live in a tank with say only 5-10lbs of rock for a few weeks without issue? Thanks for the help!
