The JBJ EFU-25 Reaction 4-Stage Canister filters utilize mechanical, chemical, biological filtration, and a 5 Watt UV sterilizer 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 the powerful UV-C lamp for pathogen and green water elimination.

Feature Details:

INTEGRATED SELF-PRIMING LEVER The innovative self-priming lever eliminates the need for manual siphoning. Simply, pump the lever up and down vigorously until the water enters the inlet and the remaining air bubbles leave the outlet.
QUICK-DISCONNECT SHUT-OFF VALVE Definitely the most useful feature to keep floors dry when carrying out routine monthly maintenance. The QUICK-DISCONNECT SHUT-OFF VALVE is an integrated tool that instantly creates a watertight seal that stops water from entering or exiting the filter. Simply lift up the SHUT-OFF VALVE handle to the vertical position to stop water flow. Grab the handle and detach and take the canister filter for convenient media replacement.
ON/OFF SWITCH FOR UV-C GERMICIDAL LAMP This revolutionary concept integrates a special UV lamp to destroy green water and polish water to crystal clarity. The accessible ON/OFF switch allows for complete user control.
HIGH CAPACITY MEDIA STORAGE The new trend in canister filters is to increase the filter storing capacity for larger amounts of chemical and biological medias. This allows for higher water quality due to more media contact through the initial pass. All filter baskets have convenient handles for removing and loading up all types of media that can be easily customized.
