I have a bunch of live rock which has been stored in 5 gallon buckets (with no water) since I
took apart my tank about 6 weeks ago. Is this rock still good to use for another reef tank or is the rock no good anymore.
any beneficial bacteria, copepods, inverts, algae, or life has definitely died off within those six weeks. the rock will need to be cured. if you place it into another tank after curing it the rock will regrow life, but it will take more time since the rock is now essentially "dead"
