Low Profile External Overflow Box (1200 GPH)

Solid construction, well packaged, great product. I used the hole saw provided and it worked without issue. I will say when working with this type of hole saw it’s important to check that it’s not crooked/wobbly in the drill. The template was easy to use and everything fit very nicely.

Very impressed with the quality of this product. fit and finish are terrific. Comes with high quality bulkheads and fittings. The pop off weir chamber attaches very securely, but will be easy to detach and clean

My tanks is very thick so the threads on the bulk head aren’t long enough to start the nut.As the directions state, double gasket with a rimmed tank. Since I can’t get the nut started I’m left trying to figure something else out. Maybe have to find different bulk heads.Also my package was missing a gasket so I’m short one.Hope I can make this work!Also the bulk heads are not threaded inside so I’m assuming I can glue PVC pipe but instructions don’t say if that’s what’s intended or not…

Was simple to set up and drill my 120 gallon tank with the included drill bit. If you have a rimmed tank don't forget to buy a couple extra gaskets for the space between the tank and overflow box. I set mine up as bean animal and it is almost completely silent.
