Brightwell Aquatics Katalyst is a bioactive filtration media designed for both freshwater and marine aquariums, including planted and reef systems. It serves as an ideal colonization substrate for beneficial microbes and provides a suitable source of organic carbon. This innovative media actively helps to decrease latent organic material, which in turn reduces concentrations of nitrate and phosphate, greatly simplifying and improving nutrient control within the aquarium ecosystem.

This bioreactive media improves water clarity through the re-mineralization of dissolved organic compounds present in the system. It offers a more stable and effective approach to nutrient control compared to methods relying solely on liquid organic carbon sources like vodka or sugar solutions. Katalyst can be effectively used in conjunction with Brightwell Aquatics MicroBacter7 and is an excellent component of a low-nutrient approach to aquarium husbandry. It is sold by mass, with 600 grams equating to approximately 946 ml, and is proudly made in the USA.

Katalyst is ideal for aquarists seeking a reliable and advanced solution for nutrient management, particularly those struggling with high nitrate and phosphate levels or aiming for a pristine, low-nutrient reef environment. Its ability to support a stable nutrient budget by facilitating active removal and re-mineralization of nutrients makes it essential for preventing nuisance algae and cyanobacteria outbreaks. This product is perfect for anyone looking to maintain a healthier, clearer aquarium with less effort in nutrient export.
