I set up a little budget side project for softies. I bought a 36" Orbit Marine IC LOOP LED (Model 4106). Although it has virtually no spread, for the price tag not too bad for what I have intended. This is over a 40g breeder (36"x 18"x 17"). The unit sits about 2-3" off the water surface. My water is overrun with microbubbles at the moment due to the HOB skimmer.
