Hi everyone just wondering about cycles for a new display refugium I'm planning on plumbing into my 8 mo. Old display tank. I have a 55 gallon with about 90 lbs of live rock with 2 clowns 1 damsel and 1 3 in. Koran angel. My refugium I'm gonna be adding is gonna have about 4 inches of dead sand with a cup or two of my crushed coral substrate. I was wondering if I am gonna have to cycle the refugium or if it will be OK if I just plumb it right in to the DT. If it has to cycle I can let it sit for a month not an issue.. I'm gonna put about half the live rock in the refuge as well. So let me know what you guys have experienced with plumbing a new refuge to an already cycled tank. Look forward to hearing from ya.
