So, I'm piecing together a new system after breaking down my 25g a while ago. It will be my old 40g breeder and a sort of modular sump design, composed of a couple of polypropylene containers (spanning a small stand and the primary one) and an acrylic sump. It will be set up as a reef that skirts the edge of a seagrass bed and I will aquascape and shape the reef structure accordingly to reflect the transition you usually see in these areas. For filtration, the tank will be filtered exclusively by an algal scrubber. This is one thing I omitted from my 25g that probably would've helped out tremendously in keeping water quality appropriately high. An algal scrubber worked quite well when I last set up this 40g, almost too well, as it stripped the nutrients from the water and required me to feed very heavily. I'm planning for primarily "sps" corals on the primary structure, with seagrass and sand-dwelling corals/invertebrates on the other side. I intend for the structure to be about 1/3 of the tank, with other strategically placed rocks. I'll have to draw up some plans a bit later to give a better idea.
Okay, so now for some specifics:
Equipment (updated 8/3/2014):
40g breeder (36" x 18" x 17" lwh) w/corner overflow
2 x 250w XM 10000K metal halides
1 Vortech MP40w ES
1 Vortech MP10w ES
1 Tunze Silence return pump (700 gph)
1 Bubble Magus Curve 7 skimmer
3 LiterMeter III, comprising one master pump and 2 remote modules for calcium, alkalinity, and top-off (magnesium in top-off water)
So, it's coming together pretty slowly, but surely. Luckily, I already have most of the equipment I need, so much of that is done. I'll be setting up a bit of a timeline with pics:
