600+GPH Overflow Box

This will transport water from one side to the other on aquariums that are not drilled for bulkheads. Comes with 1" PVC outlet & U-Tube.


This model is built to flow more and be quieter. You can go with any brand on the market, but I have taken this and improved the functionality by increasing the flow more and put a silencer on it to be quieter. Take your pick if your shopping, a noisy overflow that doesn't have a vent tube and a silencer or this one that does.
