I am currently running three 130 gallon oceanic aquariums and a single 55 gallon tank. Right now I have 12 adult Oscars, a green terror, 20 or so fire mouths, and I currently have uncounted numbers of bushy nosed Plecos. I have raised Green Terrors, Fire mouths, Oscars, and of coarse the Plecos. I have one breeding pair of Plecos and they produce a couple dozen a week or so. I have given many away and there is a fish store nearby that gives me a couple bucks each for them. I sold the majority of my Oscars for .00 each when they were about 3.5". The filter is a 40 gallon sump with two Little Giant inline external pumps. They feed a PVC manifold that has valves to control the water flow to the main wet dry/refugium, 2 of the 130s, and the other tanks. The tanks all have overflows that return the water to the sump. I have Marine land bio wheel in the sump that adds additional wet/dry filtration. I setup an auto-fill on the 40 gallon sump that is fed with it's own RO filter. This requires smaller water changes (30 gallons twice a week) and the overall water quality is much better. I keep the water temp at 75-79 the temp can fluctuate some with temp / humidity changes in the room. Yes I am this big of a geek, and it's really a testament to how cool my wife is really.
