Eshopps Prodigy L Slim Overflow Box (Large)

The Eshopps Prodigy L is a low-profile overflow assembly that moves display water to an external drainage box while occupying little space inside the aquarium. An adjustable weir provides control over the display water height, and the external box has a recessed cover.

Eshopps rates this large model for flow up to 900 US gallons per hour. Plan the return pump and drainage together, allowing for the real flow delivered through plumbing rather than choosing by pump name alone. Confirm aquarium-panel suitability, installation requirements, and clearance behind the tank before committing to the layout.

Leave the weir and external box accessible for cleaning and inspection. Test the complete system through pump shutdown and restart, checking sump reserve capacity and drain operation. An overflow is one part of the plumbing system; its nominal flow rating does not replace a safe installation and maintenance plan.
