Brightwell Aquatics Katalyst Bioreactive Filtration Media

Biological Nutrient Control for Cleaner, Clearer Aquarium Water

Brightwell Aquatics Katalyst is a pelletized bioreactive filtration media designed to support beneficial microbial activity and help manage nitrate, phosphate, and dissolved organic waste in aquarium systems.
