my old 180 broke at the top, (my fault, long story), this is my new 1. old 1 had black back, the blue back helps with the lighting. 2 250 watt halides with 2 actinic whites & 2 actinic blues. another halide over my sump for a frag tank. skimmer is missing from sump cause i was not done setting the new tank up, fish are missing from the tank cause they have another week of quarantine to go. I was a member along time ago, club was going in direction i did not have any interest in, am thinking about joining again. later
