From the manufacturer


For more than 40 years, Marineland has been committed to fish-keeping success. By applying biological science, advanced engineering and imagination to fish-keeping, Marineland continues to be one of the leaders in innovative aquatic environments and equipment.

Marineland Magnum Polishing Internal Canister Filter

The Marineland Magnum Polishing Internal Canister Filter uses two refillable chambers to house carbon or customizable filter media. The Magnum PI Canister Filter is the most versatile filter Marineland has to offer. Choose from every day, continuous three stage filtration or high efficiency polishing with the included micron cartridge. The submerged motor means quick and easy start up, no priming necessary! The Marineland Magnum Polishing Internal Canister Filter filters 290 gallons per hour and is ideal for aquariums up to 97 gallons.

Three Stage Filtration and Water Polishing

Mechanical Filtration: The Rite-Size floss sleeve traps dirt and debris. For the best results, rinse or replace 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 de-activates with use.

Biological Filtration: The dual-chamber design provides a large surface area of 153 square inches 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.

Set Up For Continuous 3 Stage Filtration

1. Place the foam gasket inside the canister and shake the canister body to properly orient the gasket. Set aside.

2. Locate the internal media container: If you wish to use alternate filter media than the included carbon, the media separator inside the container may be moved, to adjust the size of the two internal media chambers. To adjust the media separator position, unscrew both lids from the media container, and unsnap the two halves of the container. Reposition or remove the media separator, and snap the halves of the media container back together.

Convert from 3- Stage Filtration to Water Polishing

1. If present, remove the media canister and Rite-Size JH Floss Sleeve from the canister filter body.

2. Place the foam gasket inside the canister body and gently shake the canister body to properly orient the gasket. Set aside.

A TALE OF TWO FILTERS
5 Stars
A TALE OF TWO FILTERS
Ive got a 55 gallon I use to quarantine fish and plants, as well as to have some kind of "pet" in my home office other than my fry growout tanks.I had a massive explosion of algae. A real bloom. Massive cloud of algae. The worst. I tried water changes and darkness which made a minimal impact.Ive attached pictures. Isnt that what everyone comes for? The pictures.Ive had biological, mechanical, carbon bags, on this tank. an old Fluval 303, and the aforementioned water changes.I used to have a diatom filter back in the day and had thought of getting another one. I came across this by chance due to the fact that you can "charge' this filter with diatoms. I ordered cheap diatom powder from another source which was a better deal than what I could get here, and I ordered the filter on Amazon as it was the best deal, a lot less than what the pet stores carry this filter for.On to the important part.I received the filter and affixed it to the front pane of the tank where I could actually see it. IT was so cloudy and green that I could not even properly see the back panels to affix the filter. I could see almost nothing. The camera actually seems to be seeing more than I could. I put the filter on with the Micron "polishing" insert and shut the lights off for 2 days. The second picture you see with the filter moved to the side pane is the result- A small improvement. I could make out slightly more. I am not saying the filter is useless in this form- not at all. It works well and flows very strong but it was not doing a whole lot for my situation outside moving water and maybe helping incrementally over what I was already using.Then I charged the filter with Diatoms ( put the filter in a bucket of tank water, so it was submerged, and while it was running I scooped in 6 tablespoons of diatom powder / DE. Once the water is clear it is "Charged" with powder.I then put the filter back in the tank and pretended to be a functional member of society for a couple hours.The final picture is the result after less than 3 hours on the tank. Please disregard the dirty smudged glass, I had very little reason to clean the glass in the previous state.The tank is essentially crystal clear.The filter worked exactly as well-... no... BETTER than the old Vortex diatom filter I burned out many years ago.Fantastic! For the money- this is a great tool. And saved me a massive headache of keeping the lights off and continually changing water and so on hoping to turn the green tide.

5.0 out of 5 stars The Best Aquarium Filter Ever!
Reviewed in the United States on May 13, 2022
I have a simple 29 gallon tank with some (6) fresh water fish in it. No matter how often I would clean the aquarium and all the items inside it, after a few days the water would turn cloudy anyway. I tried 3 different hang on the back filter systems. They just couldn't do the work. I bought the MarineLand Magnum Polishing Internal Canister Filter and the results were fantastic. It's been 4 weeks since my last cleaning and the changing of the media which I only use carbon and a filter sleeve. The water is NOW crystal clear. I really should change the water at this point however, it is still so clear. I may wipe down the aquarium glass once in awhile but the water is always clean. Don't waste your money on those hang on the back filters. The MarineLand Magnum Polishing Internal Canister Filter IS the only way to go!!!!!!!!!! It is also very quiet with just a little hum to it.
