As I stated in the first post, the initial results were disasterous. The tank was first set up in oct 2002 and 90% of all fish losses were in the first six months. That original setup in no way reflects the very healthy and thriving setup I have today. For example, here is a picture of the tank, before several changes but after the initial addition of macro algaes. I cropped out the display area. The point is the fuzzy thing is the yellow tang. Picture was taken 30 JUL 2003. The tang is still there and picking things I don't want him picking on. Dispite emptying the water out, removing 1/2 the sand bed, adding the in tank refugium, accidently dumping 1/2 the water in the living room, mixing up new water, and resetting up the tank. (Had a bad move).
