I have limited sump space and want to expand my current Red Sea Reefer 2000XL to accommodate the new ReefMat and add a refugium. I'm planning to add another sump outside my cabinet thus creating a split sump. The idea would be to bridge these two sump compartments together with a large bulkhead. I'm planning to have the display tank drain to the first (exterior) sump where I will have a ReefMat and refugium. Then this sump will connect to the second sump beneath the cabinet where I will have my protein skimmer, probes, dose lines, and return chamber. I'm planning to use a single 1.5" diameter bulkhead and union to connect the two sumps below the target waterline. Does anyone have experience doing this? Any lessons learned here? Any additional considerations other being sure that my connection diameter is sized to my flow rate?
The only thing I'm also considering is putting in two bulkheads - the primary one would carry flow and then a second one above the water line would be in place in the event of any blockage or backup in the primary connection. Does this seem like overkill or worth the additional glass cutting and expense?
Thanks in advance for any opinions on this.
