The skimmer is fed by a Rio 800 and it has a Oceanrunner 2700 for circ. The denitrate is set up on a drip. I was actually thinking of it more like a cooling system in a car. The longer the antifreeze stays in the radiator the cooler it gets before the theromstat opens and switches what's in the motor with what's in the radiator. The longer the 10g in the sump stays in sump the cleaner it gets from skimmer and the more of it runs thru the reactors before being pushed back to display tank. At 500gph is a lot of turn over rate in the sump. Right now I have a Mag Drive 7 and 3 Hydor 2's for circulating on a 55g tank. That's a lot of flow. If I got a Mag Drive 5 that would run at about 300gph so the water in the sump would be in the sump longer and get cleaner. Just kinda brainstorming.
