Synergy Reef 16″ Shadow Overflow V2

The V2 Shadow® Overflow is the latest edition of the SHADOW® overflow system. With 3 Years of feedback from the Shadow V1, we have made some major changes to the NEW V2 Shaodw® Overflow. Here are some of the new features:

New Features of the V2 Shadow® Overflow
New Sealed Rear Lid and Rear Box Design – Redesigned Rear Lid and Rear Box flange makes a water tight seal. This helps eliminates any salt creep issues that may formed with the V1 Shadow®. We have designed the V2 Rear lid and Rear box to be virtually water tight and prevent salt creep from exiting the box.
Exterior Box Slip Fitting Openings Modified – We have modified the 3 x 1.5″ Slip fitting openings in the rear box to allow for better fitting of ANY 1.5″ PVC Pipe or Fitting. This means that you can now dry fit your PVC Pipes into the rear box holes without any worry of damaging the overflow as with the V1 Shadow®.
Re-Engineered Polymer Construction – The Rear Box Material has been changed to a proprietary new polymer blend! This new polymer allows you to use ANY type of PVC or ABS glue or primer you choose. V1 Shadow® needed special glues to work, not anymore! This means that you can use any PVC Cement that you can find locally or have on hand already. It also makes the rear box even more durable than before!
It is still 100% Injection Molded for the highest quality and most precise fitment! Easy to install and very low profile. Check out the specs of this overflow system. It can be used with as little as 400 gph all the way up to 2500 gph. If you need more flow, just add a second box.

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. Quiet operation when used to our specifications and tuned properly to your system. Our years of testing and development are what sets our overflow system apart from anything else available.

Up to 2500 Gallon Per Hour Flow Rates! That’s right. With 3 x 1.5″ Drains, this overflow can handle some flow! But if you have a smaller tank, you can use this overflow as well. We have customers using these on tanks as small as 10 gallons.
