Filter & Reactor Media

Maintaining crystal-clear, healthy water in your reef aquarium starts with the right filter media, including carbon, GFO (granular ferric oxide for phosphate removal), biopellets, and other specialty media. These filtration solutions help eliminate harmful toxins, excess phosphates, and unwanted yellowing pigments.

Specialty media like resin-based phosphate removers or nutrient control products can target specific contaminants, giving you even more control over your tank’s water quality. Using high-quality filter media in reactors or media bags ensures your reef tank remains clean, vibrant, and free from harmful pollutants.
