My JBJ is 3 years old. I redid the tank in Sept 2010, and converted it to a sps dominated tank. Currently the tank does not run a skimmer, it had a Tunze 9002 in a HOB fuge. The only other piece of equipment is a West Coast chiller. Lighting is Radium 20k metal halide. Power heads include a Koralia 4 and Koralia 2. Plans for the tank include just letting the sps and zoanthids grow, and controlling the growth of the soft corals. Eventually I am going to remove all the GSP growing on the back wall. Fish: Pair of B/W misbar clowns and a old YWG.
