- Eclipse M Overflow Box - 800 GPH (OPEN BOX) - Eshopps
Quiet, Slim, Plug & Play
The Eclipse aquarium overflow system consists of a slim black box that is mounted inside of your tank and a clear external box that mounts outside of your tank, to transport water down to your sump with as little noise generated as possible. The DIY project only takes a few minutes to complete and compared to HOB style overflows, the Eclipse has a fail-safe design that includes a minimum of two drain bulkheads for a Herbie method of plumbing.
The internal/external design for the Eshopps Eclipse Overflow Boxes creates a minimalistic design inside the aquarium, extending less than 1.25" inside the aquarium. Water can flow through the 1/4" teeth in the wet-side of the overflow, and then through the included bulkhead into the external box that holds additional bulkheads to let the water drain down into the sump. It is required to drill your aquarium with the Eclipse overflow but drilling is fairly simple and with the included glass drill bit and drill guide. The guide helps you set the perfect water level for your aquarium and then lets you know exactly where to drill your hole(s).
Selecting the right overflow for your tank can be confusing but it is a pretty simple formula, just take the total flow produced by your return pump and select an overflow that can handle that overall flow rate, and still be able to fit inside of your aquarium. In most cases, we will recommend using an overflow that is +1 sized for your application. That lets you upgrade to a larger pump or tank in the future, with an added safety benefit of being able to handle additional flow if one drain gets clogged or restricted.
Installation Tip - When installing the bulkhead gaskets we highly suggest placing one between the inner overflow box and the aquarium. The other gasket should be placed between the external box and the bulkhead nut.
