Refugiums

A refugium is one of the most effective ways to naturally improve water quality in a saltwater aquarium. By creating a separate space for macroalgae, copepods, and other beneficial organisms, refugiums help reduce nitrates, stabilize pH, and support a more balanced reef ecosystem. Whether you're adding one to your sump or setting up an external module, a well-maintained refugium offers long-term benefits to your tank.

This collection features a range of saltwater refugiums, including in-sump chambers, hang-on-back styles, all-in-one units with dedicated compartments, lighting, and microfauna to jump start your refugium. They're ideal for nutrient export, pod cultivation, and even light-blocking purposes during reverse photoperiods. A refugium for reef tanks not only helps with stability—it can also serve as a safe zone for microfauna and plant life to thrive.
