I have a 125 gallon salt water reef tank that has been going since June of 09. If any of you guys think that welding is an expensive hobby, do not get into reef tanks!
My tank consists of about 175lbs of live rock and about a dozen different corals. I have three 250 watt metal halides and 8 39 watt T5 actinic lights (bright blue).
I have a blue tang, yellow tang, two clown fish (one black and white, the other orange and white) a starry blenny, a fire fish, purple psudochromis, royal gramma, fire shrimp and a bunch o snails and hermit crabs.
