We have recently re-started our SW tank and are using the live rock that we used before. The rock has never been completely out of the water (except at some of the higher parts). But, it has been living without the pump on for awhile. My question is are the inhabitants still likely alive in there and if there is a chance of this, how is a good way to tell. Also, is it a good idea to purchase a smaller piece or two (of live rock) and add to the tank now? Thanks for your help!!! :squigglemouth:
