I'm in the process of setting up a 30G refugium for my 55. The 55 has been up and running for about four months now. After a hectic initial cycle in which I had no clue what I was doing, everything has come around nicely (thanks to the helpful reefers on wamas.org). I've just added 50lbs of SD and my water. I'm going to throw in 10# +/- of live sand here in the next day or so. I've got a refugium culture kit on hold which will be shipped as soon as I'm ready.....
My question is, when will I be ready? Should I let the fuge go through a cycle with the live sand/rock before adding the culture kit? When should I hook up the pump to my main tank in order to start reaping the benefits?
Thanks.
