Is your DSB in your DT, sump, or both? I am asking both of you, carey and purevil, just because I am following both of your threads and want to see what you'll end up doing (considering you are pros and I am the newbie!)
Since I am also following both their threads too, I thought I would chime in too... I have a DSB in both of DT and sump. I'm also a newbie, I'm only on my second SW tank and my first one was over 5 years ago and only had it running for 6 months before I had to move. But in my first tank as well I had a DSB in both.
