Eshopps Eclipse Overflow Kit (Medium) Eshopps Eclipse Medium Sump Overflow System The Eshopps Eclipse Overflow Kit (Medium) creates a clean and compact connection between a drilled aquarium and an external sump. Its 8-inch internal surface-skimming box extends approximately 1.25 inches into the aquarium, preserving valuable display space while providing a wider overflow area than the Eclipse Small. Rated for return flow up to 800 GPH and aquariums up to 100 gallons, the Eclipse Medium uses an internal and external box configuration with two 1-inch drain bulkheads. The supplied drilling template and 60 mm holesaw help position and create the transfer opening in a suitable aquarium panel.

Confirm that the intended glass panel is not tempered and can be safely drilled. Leave enough clearance behind the aquarium for the three-inch-deep external box, drain fittings and connected plumbing. The 800 GPH rating represents the maximum recommended overflow capacity. Return-pump selection should account for plumbing head pressure and should leave reserve drain capacity rather than operating continuously at the system's absolute limit. Eshopps Eclipse Medium Installation Directions Lower the aquarium water level below the installation area and secure the supplied template at the desired height. Check the position carefully because the template establishes the overflow location and operating-water level. Use the included 60 mm holesaw to drill the opening while keeping the cutting area wet and following proper aquarium-glass drilling procedures. Assemble the internal and external boxes with the supplied transfer bulkhead and gaskets, then install the drain bulkheads and standpipe. Complete the plumbing and perform a controlled fresh-water test to confirm leak-free operation and adequate emergency-drain capacity.
