Marineland Magnum Polishing Internal Canister Filter (Aquariums Up To 97 Gallon)

Whatever you are passionate about - freshwater or saltwater, big or small, beauty or science, make your aquarium your own. The Marineland Magnum Polishing Internal Canister Filter offers versatile aquarium filtration for your aquarium up to 97 gallons. Choose from everyday powerful, continuous three-stage filtration or the high-efficiency micron water polishing option. This compact and versatile filter is capable of filtering 290 gallons of water per hour. The self-priming, submerged motor means quick and easy startup. Its dual-chamber, refillable media chambers house carbon or customizable filter media. It includes a Marineland Black Diamond Premium Activated Carbon and a Marineland Rite-Size JH Floss Sleeve. Replace the filter every two to four weeks (replacement filters are sold separately); clean the micron cartridge monthly. Clean, sparkling water is the mark of a healthy, thriving aquarium. The amount of filtration needed to maintain an aquarium depends on a number of variables. These include tank size, individual maintenance habits, and fish population.

Internal Canister Filter

It features a submerged motor for quick and easy startup.

Versatile Filtration

The two refillable chambers house carbon or customizable filter media.

Micron Water Polishing

This feature offers high-efficiency polishing with the micron cartridge (included).

Mechanical Filtration

The Rite-Size floss sleeve traps dirt and debris. For the best results, rinse or replace the sleeve monthly.

Chemical Filtration

Black Diamond Premium Activated Carbon removes odors, discoloration, and water impurities. It is recommended that carbon is replaced monthly since carbon deactivates with use.

Biological Filtration

The dual-chamber design provides a large surface area of 153 square inch for the growth of Bio Spira, a beneficial bacterium that neutralizes ammonia and nitrites.

Water Polishing

The reusable pleated micron cartridge efficiently removes fine debris, leaving water crystal clear. The cartridge may be charged with diatomaceous earth to further increase efficiency.
