I've read many comments in other threads on this but I want to be sure I'm good to go before I damage my tank. My 55g has been up-and-running for about 2.5 months now and all is well. Ammonia, Nitrate, and Nitrite are all at zero and PH
and Salinity are where I want them and are stable. I do have a Calcium issue which I'm trying to deal with but I think that's unrelated to this thread. So ... I want to add some more live rock, not a whole lot, maybe 15-20 lbs or so to fill a gap created when I removed an ornamental sea fan that just kept getting uglier and uglier with algae build-up. I've read that adding cured live rock should be fine and result in a minimal spike or maybe none at all. I trust my LFS
to sell me truly cured LR
but it will take up to an hour to get it home and into the tank. Can I go ahead ???
