Saltwater Reef Tank
by Don Geddis

This 250g reef tank started in November 2005. The initial livestock came from my previous 55g reef tank.

The major part of the display tank is a community reef, including fish, corals, invertebrates, live rock, and live sand. There is also a partition 1/3 of the way on the left side (which allows water to cross but prevents large animals from switching sides). The smaller section holds seahorses, which share much of the maintenance requirements of reef fish (and thus can share water), but which thrive better in their own section (because they prefer low current, low light, and are such slow hunters that they might starve in a tank with fast, aggressive fish).

250g system

192g display (66"x28"x24")
- 1/3 seahorses
- 2/3 reef
40g refugium (36"x15"x16"")
40g sump (36"x15"x16")

2x250W 10K Metal Halide
2x60" VHO Actinic White
3 SCWDs (6x2 = 12 returns)

I originally imagined that I would design a custom (multi-level!) tank system of my own, but without any building experience I decided it was wiser to get professional help with my first major system. This tank was built by Nemo Marine Systems in San Jose, CA.
