A slim black weir box sits inside the tank and takes up just 1.25 in of depth, water passes through a 1.5 in transfer bulkhead in the back glass into the clear external box, and two or three 1 in drains carry it down to the sump. The drilling template and 60 mm hole saw are in the box, so you can convert a standard tank yourself.

It flows through the transfer bulkhead into the external box on the back of the tank, then out through the 1 in drain bulkheads in the bottom. With two drains you can run a Herbie setup: one full siphon drain that runs silent and one open emergency drain that only carries water if the siphon clogs. The Eclipse L adds a third drain for a Bean Animal configuration, a siphon, an open channel and an emergency, which is the quietest and safest drain arrangement in the hobby.\u003c\/p\u003e\n\u003ch2\u003eFeatures on Every Model\u003c\/h2\u003e\n\u003cdiv class=\"aq-features\"\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eSlim 1.25 in internal box\u003c\/strong\u003e\u003cspan\u003eThe black weir box intrudes only 1.25 in into the display, far less than a traditional internal overflow.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003e3 in external box\u003c\/strong\u003e\u003cspan\u003eThe clear external box is 3 in deep, so the tank still sits close to the wall.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eTemplate and 60 mm hole saw included\u003c\/strong\u003e\u003cspan\u003eSet the water line and mark the cut with the drilling template, then bore the bulkhead hole with the included hole saw.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003e1.5 in transfer bulkhead\u003c\/strong\u003e\u003cspan\u003eMoves the water through the back glass.

Tape the template to the outside of the back glass at the height it indicates, keep the hole saw wet and let it cut at low speed with light pressure. Deburr and dry the hole, fit the transfer bulkhead with its gasket on the inside of the glass and tighten by hand only. Hang the external box on the bulkhead, plumb the drains with 1 in PVC, start the return pump slowly and adjust the siphon valve until the water in the external box holds steady with the emergency drain dry.\u003c\/p\u003e\n\u003ch2\u003eRecommended Pairings\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/squeakysaquatics.com\/products\/simplicity-dc-return-pump\"\u003eSimplicity DC Return Pump\u003c\/a\u003e, controllable flow you can dial in under the overflow rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/squeakysaquatics.com\/products\/trigger-systems-titanium-34-sump\"\u003eTrigger Systems Titanium 34 Sump\u003c\/a\u003e or \u003ca href=\"https:\/\/squeakysaquatics.com\/products\/icecap-15-reef-sump-v2\"\u003eIceCap 15 Reef Sump V2\u003c\/a\u003e for the cabinet below.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/squeakysaquatics.com\/products\/filter-sock\"\u003eAquarium Filter Sock\u003c\/a\u003e to catch debris where the drains enter the sump.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/squeakysaquatics.com\/products\/loc-line-nozzles-3-4\"\u003eLoc-Line 3\/4 in Nozzles\u003c\/a\u003e to aim the return flow.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/squeakysaquatics.com\/products\/eshopps-power-flow-hang-on-overflow-box\"\u003eEshopps Power Flow\u003c\/a\u003e if you would rather hang an overflow than drill.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDoes my tank have to be drilled?\u003c\/strong\u003e\u003cbr\u003eYes.
