I keep looking for that RBTA you use as your avatar on RC ...
I guess it's not this tank ..
Nice pictures, BTW.
I don't know why, but I've always been fond of 20g reef tanks. I have a little 20g with a wee little reef, some scraps from my other tanks, some frags, and a pair of fairy wrasses in there. I use a 150W 20000K double-ender. I like it, although for intensity you might want to look at 10000K. The 20000K is cool for colour but lacks a strong punch on the insensity compared to whiter lights.
