The Elos SUMP is designed to be flexible, functional and beautiful. Made entirely of glass with a compact, yet complete, filtration design, the Elos SUMP is a complete external filtration system that allows the user easy access to all elements of filtration. With a built in freshwater reservoir and an Elos Osmocontroller II, maintaining proper salinity and an optimal water level in the sump is simple. The Elos SUMP utilizes our unique, Variable Velocity Chambers, which allows complete water filtration before returning to the display aquarium. Because a sump will hold pumps, heaters, protein skimmer, filter materials and top off controller, we have designed an ABS top to manage cords, tubes and control evaporation. There is also an ABS bottom trim to protect the bottom glass of the sump. Finally, the Elos SUMP is delivered with all the necessary pieces to make installation easy. For optimal performance of the Elos SUMP, see our Filter Materials section.
