Marineland Magnum 350 Canister Filter


The Marineland Magnum 350 canister filter provides up to 350 gallons per hour of water cleaning power. Quiet operation and the ability to customize intake and outflow makes this filter a beneficial addition to both freshwater and marine fish tanks.

The bottom mounted motor is completely sealed and waterproof and carries a three year warranty. Setup of the Marineland Magnum 350 aquarium filter is simple and all filter media is included in the box. Not only is this canister filter exceptional as a regular mechanism for removing debris and waste material from your tank, it can also be easily converted to a water polishing system.

When water enters the Marineland Magnum 350 canister filter, it is forced up through filter media with no chance of bypass. This ensures that the mechanical, chemical and biological filtration maintains maximum effectiveness. Included is a fiber sleeve, activated charcoal and a reusable micron cartridge. This filter can also be used with a bio wheel, which provides the perfect environment for beneficial bacteria to colonize.

All this filter’s technological aspects work together to provide clean and healthy water for your fish and other aquarium inhabitants. Its customization capabilities allow for multiple uses depending upon the particular needs of the fish tank setup.

Aquarium Advocate Review:

I have used the Magnum 350 canister filter in the past and used it for years. I used to run 3 of them on my 240 gallon and also used one on an 80 gallon. My overall experience with this canister filter has been good.

These canister filters are very simple and easy to use. It has metal clips on top to release the lid and then the media compartment pulls out in one motion. The lid easily comes off the media compartment and you can fill it with whatever you want. There is a sponge sleeve that goes over the media compartment that traps waste. This sponge can be re-used over and over. I suggest rinsing the sponge in aquarium water so that chlorine does not kill the good bacteria.

I like this filter. With that being said, there are some things I don’t like about it. Maybe i’m just slow, but I had the hardest time with the hose release valve. In order to disconnect the hose to take the filter outside you have to deal with the in-line connector. It’s not hard to take apart, but it is hard to get it back together just right.

There is quite a bit of unused space in this filter. The media container and sponge do not take up all the room in the canister. The design doesn’t allow you to stuff this extra space with extra media because (I don’t think) much water will pass through it.  Another thing to consider is there is only one media compartment. Other filters offer several compartments to fill with different media.

The Bottom Line: This is a good, reliable filter. I have had a lot of good experience with it. It is very easy to use, with the exception of the hose release valve. If you want something more versatile, that can house lots of different media, this is probably not the filter you want. If you want something easy, pick this.
