Reaction 4-Stage Canister filters utilize mechanical, chemical, biological filtration, and UV sterilization for a balanced aquarium. Water enters the canister via the intake strainer and is guided through a large sponge to trap particulate matter. The water then reaches 500g of activated carbon to remove harmful dissolved organic compounds. Water is directed over the ceramic rings that offer a tremendous amount of surface area internally and externally to grow beneficial aerobic bacteria that break down harmful ammonia and nitrite to nitrate. All filtered water then passes through our powerful UV-C lamp for pathogen and green water elimination.


Reaction-4 Stage Canister Filters are equipped with the most advanced features to provide high
performance and make routine maintenance quick & easy.
