The Denitrification Catalyst is a specialized supplement designed to be used in conjunction with Maxspect Nano-Tech Anaerobic Blocks. Its primary function is to create an ideal environment that fosters the growth and proliferation of anaerobic heterotrophic bacteria within your filtration system. These beneficial bacteria are crucial for the process of denitrification, efficiently breaking down nitrates into harmless nitrogen gas, which helps maintain pristine water quality and a healthier environment for your aquarium inhabitants.

This package includes five individual catalyst pieces, providing a long-term supply for your filtration needs. For proper use, one catalyst piece should be placed between two horizontally stacked Maxspect Anaerobic-Blocks within your sump. To ensure peak performance and consistent nitrate reduction, it is recommended to replace the catalyst every two months. The Anaerobic-Blocks themselves have a longer service life and typically require cleaning or replacement every six months. This product is versatile and can be used effectively in both saltwater and freshwater aquariums.

This product is essential for aquarists who have invested in the Maxspect Nano-Tech Anaerobic Block system for biological filtration. If you are aiming to maintain an ultra-low nutrient system and actively manage nitrate levels, these catalysts are a necessary component to maximize the efficiency of your blocks. By providing a dedicated food source for the anaerobic bacteria, you supercharge the denitrification process, making it an indispensable consumable for reef keepers and advanced aquarists seeking ultimate control over their water chemistry.
