I have the same thing... that way if I want to shut my system down but I don't want the water in the DT to drop till the siphon breaks, I just close the valves.
I couldn't tell you the actual specifics of the bulbs. They are just small T5 bulbs, like I said the tank was a freshwater setup I got for free. lol I will look later, thanks for the compliments, I need to clean it up a little more, but it is night and day from before I started.
What substrate did you use for your current dsb? Have you actually seen a difference? I run 0 trates now and I have like 1 inch to 2 inches...
