We have a LFS that has live rock for $5/lb. I was wondering if I could put this in my brackish tank will be putting a GSP in it. I know the bacteria would die off, would I have to rinse the LR in tap water or let it soak to help so I don't get an ammonia spike or boil it. The tank is currently cycling and I have aragonite for substrate. I will eventually go to full marine as the GSP gets older. SG is 1.009 P.H. is 7.8-8.0. If this won't work what kind of rock could I use then. Thanks for your help.
