Okay, as promised, new pictures of the reef tank.
Now, I realize that these look exactly like the old pictures of the reef tank, but you'll have to take my word for it -- it's much cooler with the new LEDs, especially when you get a disco strobe effect by turning all of the banks of lights up all the way. (In retrospect, perhaps we should have double-checked our assumptions about how much current these things draw before we decided on a power supply...)
I chose this picture because you can see that the little Xenia has moved off the plug and onto the rock. I might be sorry that I allowed it to do that someday, since everyone else considers these things weeds, but I still think it's cool. My coral are walking around!
This is the finished product. You can tell it's the finished product because I didn't bother to wipe off the water that condenses on the splashguard as it's sitting on top of the tank. I'd take a picture with the LEDs on, but I don't wish to blind myself.
Anyhow, so far, so good. The house hasn't burned down, the coral haven't been obviously damaged, and I'm happy with how it looks. It might be time to get some more coral...
