Cutting-edge refugium with patent pending design optimizes natural filtration and skimmer performance for superior aquarium water quality. Eshopps 3rd Generation Refugiums feature an innovative dual-chamber, dual-water channel design that diverts incoming water to a dedicated refugium and skimmer chamber for better nutrient export.

The unique design of the Eshopps 3rd Generation Refugiums allows macroalgae in the refugium chamber and the protein skimmer in the skimmer chamber to function unimpeded. The result is efficient processing of dissolved and undissolved organic waste materials through two forms of aquarium filtration. Skimmer chamber easily accommodates in-sump protein skimmers and refugium chamber is the perfect place for nutrient scrubbing macroalgae such as Chaetomorpha Algae.

Requires Return Pump, Return Line, and an Overflow Box for aquariums that are not drilled for plumbing. Additional Micron Filter Bag sold separately. Use the brilliant, energy-efficient Eshopps Curve Refugium LED Light to support healthy macroalgae growth in refugium chamber of your Eshopps 3rd Generation Advanced Series Sump.

Eshopps 3rd Generation Reef Sumps include Bulkhead Fitting, 3-foot Flexible Hose, Micron Bag, and Sump Filter Foam.

Eshopps 3rd Generation Refugiums
Sumps are beneficial additions for both fresh and saltwater aquariums. In the most basic terms, a sump is an additional receptacle plumbed inline via a Siphon Overflow box, or bulkheads in pre-drilled aquariums. It will provide additional space and increase the total volume of water in an existing system. Sumps can be as basic as a supplementary aquarium, a large plastic container, or as part of a more elaborate wet/dry trickle filter or refugium. With some basic plumbing techniques, a sump can be installed to most aquariums to provide numerous benefits.

Additional Space for Equipment
A sump benefits an aquarium by providing extra usable space. Think of it as an "add-on" to your existing aquarium. It is the ideal location for equipment such as heaters, thermometers, and protein skimmers. Since most people keep a sump beneath the main aquarium or hidden from view, equipment that can clutter or obstruct aquarium viewing can be neatly tucked away.

Quick Setup Guide
NOTE: The Eshopps Wet Dry Filter requires an appropriately sized submersible return pump. The maximum flow rate of the pump must match the maximum flow rate of the overflow box for proper operation.
