Overflow Height Spacer

Every tank is slightly different, and that means any protective lid has to be specialized to it. Some tanks have overflow boxes that are lower than the top of the tank glass, meaning that any will bow in the back due to lack of support. 

Examples of tanks with this style overflow are:

• Red Sea

• AquaForest Oceanguard

• Waterbox Cube and AIO

• Planet Aquarium Tideline AIO

The Top Lids Overflow Height Spacer fixes this issue. Made specifically shaped and sized for each individual overflow box, the Overflow Height Spacer raises the top of the overflow to be able to support any aquarium lid.

Top Lids for some of the tanks above come with Overflow Height Spacers (or similar pieces), and others don't. Be sure to read the Product Options at the top right of every corresponding Tank Product Page, to learn more about what each Top Lid Project includes for each Tank.
