The Shadow™™ Overflow is the evolution of the Synergy Reef® overflow system. Now 100% Injection Molded! Featuring a removable weir for ease of maintenance and our molded design for fail-safe operation. Our ultra slim design has revolutionized the aquarium overflow and how aquariums get water into their filtration systems. It is a very simple to install, plug and play overflow system. Completely quiet operation when used to our specifications. Our years of testing and development are what sets our overflow system apart from anything else available.

VTeeth™ – Our new Velocity Teeth allow for an even surface skimming flow into the overflow. This maximizes the surface skimming capabilities of the overflow as the flow rate increases. This also allows us to have a very small water level differential. Injection molded VTeeth™ are smooth without any rough surfaces, this provides a continuous smooth flow.
U-Flow™ Pipes – Now included with every Shadow™ overflow is a set of U-Flow™ pipes. We have designed these fittings to maximize space inside of the outside rear overflow box. These compact fittings are not available off the shelf anywhere else. They allow us to fit our 1.5″ Fittings into such a small space.
Being reef hobbyists ourselves, we spent years working on the design of this overflow. We tested hundreds of variations and options before we came to this design. Our fundamental goal was to create a low profile and quiet internal overflow box, while maintaining the flow rates desired by reef hobbyist. We wanted an overflow system that everyone would want to use. Originally we partnered with designed the overflow to be built by hand with flat sheets of acrylic. Using flat sheets for an intricate design like we envisioned was not possible. Designing the overflow with 3D software allows us to add features not possible when building it by hand out of flat acrylic. As we moved forward with the design we wanted to make a product that could be produced for everyone to enjoy. Injection molding was the answer. While it took us a long time to design and manufacture this overflow, it now is exactly where we wanted it to be. This overflow system was designed by Synergy Reef Systems in the USA!
Injection molding allows us to make every part exactly the same. Every part is molded with the same tolerance and specification. Unlike hand build models, molding allows the Shadow to be precise in fit and form. We use the highest quality US produced Polycarbonate and ABS in our molding process. Our quality is second to none! There are lots of imitation overflows out there, but ours is the highest quality available, period!

This will be a self install kit. You can drill the tank and install this yourself! Instructions are located here: 16″ Shadow® Overflow Installation Manual
Drilling template is included with the overflow and we recommend you use the template when the overflow arrives to align it perfectly. But if you need the drilling template .pdf it is located here: 16″ Synergy Reef Overflow™ Drilling Template .pdf
