I cut all the xenia off one piece of rock I have and want to put it in my 10g tank, but I don't want the xenia to grow back - it's in my sump now and still has a thin layer of tissue covering the rock.
what's the best way to kill off the remaining tissue? should I just soak it in RODI water for a day?
