Looks similar to mine, except my fuge is just a compartment in my 20gal sump. Is this a flow-through design? Is all the flow draining from the tank going through the fuge? I have maybe 1/3 of the flow through my sump directed through my fuge. How big is the main tank? If its decent sized and this is a straight pass-through without any redirect, something like 500-800gph through the fuge is too much IMO. More information por favor?
