The Marineland® Magnum® Polishing Internal Canister Filter uses two refillable chambers to house carbon or customizable filter media.

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.
Magnum® Polishing Internal Canister Filter is rated 3.6 out of 5 by 28.
Rated 5 out of 5 by from Powerful Little Filter I didn’t really believe how a small little thing like this could possibly work in aquariums over 90 gallons until I saw the circulation it makes in my 40gal long tank. This thing moves water like crazy! Sadly my dog ate the media container, so I can only speak for the micron filter, but it does a great job of picking up the fine particles from my new sand substrate. I’ve been hoping to find a new media container online, but no such luck, so that’s a small bummer. I do wish that parts like that were sold online!

Rated 5 out of 5 by from Best water polisher. I bought this product a few weeks ago and am astounded at how well it works, it polishes and can be used as a full time filter for the price of a cheap external filter.

Rated 5 out of 5 by from Love it Had problem with it sucking in water around the top but ask and received the answer and it is again doing a great job. Thought we were doing a good job of keeping it clean but now we know how to really clean it and it is not hard.Love this filter

Rated 1 out of 5 by from Loud after 1.5 weeks I have this filter for approximately 6 months. After approx. 1.5 weeks, the filter becomes very loud. I have cleaned the propeller assembly and motor to no avail. Not sure I would recommend this

Rated 1 out of 5 by from Flow issues I bought the filter 6 months ago, and it worked great at first. Now it doesn't expel water at all. Tried to fix it, cleaned everything, still no flow. Very disappointed

The extension tube flys off the canister when you,turn it on

Asked by: Sparkymark
It has a tiny little hole and there is a tab it must snap onto, on the shroud. So make sure you have it snapped on properly. Also, it sometimes helps to adjust the diffuser, change the direction in which it is pointing. BREX

Will I ever have to replace the filter sleeve and carbon 

Asked by: Dalpal
Yes, of course. Carbon should be replaced at least every four weeks, if not more often. The filter sleeve can be rinsed and reused until it is too stretched out, usually just a few months. BREX

I just got a Magnum and it worked efficiently for one week but the flow reduced so I decided to recharge the pleated cartridge but now the filter won't start. The pump just makes a humming sound.

Asked by: Anou
no luck...could you send me a new powerhead? Marineland products are not available in this part of the world.
