Yes I do have a pretty complicated filter setup...Sump with bio balls and prefilter,monster skimmer,10 gallon refugium,UV,and a magnum for additional chemical filteration.all running off the same return pump.A PLUMBERS NIGHTMARE(or wet dream,depending on how you see it)..But the tank is only a 130.Plus those pics are old.I don't have that many fish in there now.That was an overstocked nightmare.
