- Eclipse M Overflow Box (800 GPH) - 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.

Great overflow!!! By Steven on 5/9/2019Steven would recommend this product to a friendAfter reading numerous reviews about the Eshopps overflow some good some bad I decided to give it
a try and I couldn't be happier with the overflow. Installation was a breeze and had it all said and done in in less than 10 minutes even with this being my first time drilling a tank!!!! Great product will be installing another on my next set up
Love these overflows By Scott on 7/18/2018Scott would recommend this product to a friendI just installed my 3rd medium Eshopps Eclipse on my 90 gallon. Their holesaw are fantastic and included, free. So fast and easy. Very quiet if use a gate valve to fine tune that is difficult with a ball valve. I submerge the overflow pipe one inch below the water line in the filter sock. High quality. No worries over a flood. I always go with an extra large sump to not worry about returns back siphoning or anything back siphoning or even a run away ATO. I do have a synergy overflow on my 150 but Eshopps products are just as nice.
Connecting sumps the best way By Scott on 5/10/2018Scott would recommend this product to a friendEvolving from canisters to sumps is like the difference between day and night. So many more benefits with sumps as all Canisters end up leaking. Installing overflows is actually fun. Having installed synergy and now Eshopps overflows, I think Eclipse is a great product with a fabulous price especially with the holesaw included. Thick, well bonded, heavy duty construction. You always want the template as high as you can place it. Holesaw was good quality. Installed easily. I usually use a little silicone grease on the gaskets. Tighten finger tight then another quarter or half turn with pliers. I am ordering another for my other tank.
Well built - Great Value By Anthii on 2/23/2018Anthii would recommend this product to a friendI received this today and I have to admit - that I'm not really someone who buys a lot of eshopps products. That said - I really like this product. I'm a fan of Herbie or Bean Animal overflows and the quality of this overflow is really great. It all acrylic, has all the bulkheads and gaskets you'll need and the best part was getting the drill bit to go with it. If you're going to drill a tank for an overflow - this (or either the Sm or Lg depending on need) is the way to go.
Hello! What is the size of the two pipes in the buttom of the ESHOPPS - ECLIPSE M OVERFLOW BOX? Best regards Viktor
This overflow does come with two 1" slip bulkheads so that will glue directly to 1" PVC. Have a great day!
