ECCO LINE SUMPS are in-stock and ready to ship with no lead time.

The ECCO Line Sumps are designed to be the last sump you’ll ever buy - feature-rich, modular, and built to grow with you as your system and the hobby evolve. Thoughtful engineering allows the ECCO design to function effectively as either a Berlin-style or Triton-style sump, giving you flexibility in filtration methodology from day one.

The ECCO-4418 Rollermat Sump is a high-capacity, roller-ready model engineered for large reef and saltwater systems that demand performance, flexibility, and clean organization. Constructed with robust 3/8″ thick acrylic on the top and sides to prevent warping, it features a professional modular layout with dedicated chambers for roller filtration, protein skimming, refugium, and return flow, enabling efficient staged filtration and quiet operation.

Designed to support major roller filtration systems—including Clarisea SK-3000 & SK-5000 Gen 3, Smarter Reefs AIO units, and the Red Sea ReefMat 500,1200—the ECCO-4418 is built for long-term adaptability. Features include an optional filter sock plate for mechanical filtration choice, adjustable water height, silent submerged inlet, removable bubble trap, swappable and expandable bulkhead plates, dual heater holders, and integrated probe and dosing ports, making upgrades and customization simple.

The ECCO-4418 combines minimalist aesthetics with serious filtration capability - start smart, finish strong, and give your reef everything it needs to thrive.
