Nice tank! I have had my RSM since February. I love the lighting, and the lack of heat that comes with it. I have had some acros and birdnests for a few months now that have kept color and grown at a faster pace then expected.
When nanotuners or someone else makes a halide upgrade I might consider, but it will have to come with t-5 as well to light the ends of the tank. I think halide would be tough to distribute light to the coners with the buld so close to the water.
