OK, fourth tank and probably the biggest. Realized I like LPS better overall than SPS, so not going to try for a Mixed Reef (at least not for the first year), so just thinking of this as a LPS tank. Got an SC Aquariums 240, which should be here in a month or so, which is kind of a blessing in disguise because it's letting me take my time setting up the sump/plumbing/aquascape. Got Marco Rock shelf and foundation rock and really love the way it looks. Here's what I've assembled so far with most of these mortared together, but still waiting on a few bags of the Marco Nano rocks to finish it off. Pretty happy with the shelf rock.
