I have some live rock in a cube with red velonia all over it. I am shutting down the cube and was wondering if i should put the live rock in my 135 or just let it dry out to kill everything off and then put it in my 135 to be reseeded. I hate to kill live rock but Im afraid if the velonia took over my 135 I might not be able to find enough emerald crabs to clean it up. Any advice?
Thanks
