I have just acquired about 20 lbs of live rock from a co-worker who took down his tank today. He had the rock in his 20gal tank for about 1.5 years. I am going to bring it home afetr sitting at work all day today and am not sure if it will be OK to add it directly to my tank. I currently have a 20gal tank with about 10lbs of live rock 1 cleaner shrimp, 1 lawnmower Blenny, 1 Figi Damsal and a pencil urchant along with a hairy mushroom.
Any Suggestions would be appreciated.
I have been reading several threads talking about cycle's and Amonia spikes. Because this is established LR Do I need to be concerned??
Thanks
John
