Brightwell Aquatics Katalyst is an advanced bioactive filtration media engineered to provide an ideal colonization substrate and a suitable source of organic carbon for beneficial microbes. These microbes are crucial for the uptake of nitrate and phosphate in aquariums, effectively decreasing latent organic material and significantly reducing nitrate and phosphate concentrations. This innovative media simplifies and enhances nutrient control, offering a superior alternative to methods relying solely on vodka or other alcohol/sugar solutions as organic carbon sources.

This 3.2 kg (7 lbs) package, providing approximately 5,000 ml of media, is safe for use in all freshwater and marine aquariums, including planted and reef systems. Katalyst improves water clarity through the re-mineralization of dissolved organic compounds present in the system. It is made in the USA and sold by mass, ensuring consistent quality and performance for your aquarium. Its unique formulation allows for integration with products like MicroBacter7 and supports a low-nutrient approach to aquarium husbandry.

Brightwell Aquatics Katalyst is ideal for serious reef aquarists and freshwater hobbyists seeking a highly effective and simplified approach to nutrient management. It is particularly beneficial for those looking to maintain pristine water quality, reduce the need for frequent water changes, and support a vibrant, healthy aquatic environment. By providing a stable and efficient platform for beneficial bacteria, this media helps prevent algae outbreaks and promotes the long-term health and clarity of your aquarium.
