I had a 300 reef tank with 450 lbs of live rock and a whole lot of sand.
The lights, pump, and filter have been turned off for almost a full year.
I'm getting ready to start a smaller tank (95g) and I am wondering if it is o.k
. to reuse the old live rock.
It has always been submersed in salt water. There is no film on the water or foul smell coming from the tank.
What about the sand? Can I reuse that too?
