Rated 4 out of 5 by njsm excellent filter
My tank water was cloudy and had a tannin problem. I had tried many products and filter medias before i heard about this filter. I bought the filter and marineland black diamond carbon (one of the best carbons ive used and very reasonably priced). I run the filter full time with carbon and ceramic rings.
The first day i started this filter the water had already cleared alot within tge hour. And the tannins were dissipating at a good rate.
3months later.... the tannin problem is gone and water changes are to a extreme minimum in comparisin to before. Crystal clear water and lower nitrates just as promised. I will be buying more of these in the future.
My ONLY complaint is the mesh screen on the media basket isnt fine enough. Thus limiting the filter media you can use and replacing carbon is messy. But it does a good job as designed.
4/5 review for versatility
5/5 for performance

Rated 1 out of 5 by nothap3 good for a month
I've personally onto Magnum 350 both bought was in a six month. The first one that I owned the top of the canister had actually cracked of wall in use and flooded downstairs ruining my hardwood floor. That one was less then 2 months old and cleaned regularly. The second has been running for about a month or so and has ceased to properly filter the waterI've cleaned it multiple times trying to get it to circulate properly and it still will not. Im never buying a Magnum 350 again. Period. End of story

I just purchased a Mag 350 to go along with my C-360 in my 75gal freshwater tank. I've always been a "over-filter" type of guy and Marineland does the trick. The Mag.350 is a design that proves "If it works,don't change it". I'm glad you folks did not.

Rated 5 out of 5 by Vash Easiest filter (next to the emperor 400) I've ever used!
I have a 60 gallon freshwater tank with a 350 magnum canister and the water is the cleanest I've ever seen in a tank! From the under 30 minute set up to the 10 minute cleanings no other filter is this easy to use. The micron filter's snug fit removes all particles from the water over night. The motor is virtually silent as well. I've even come up with a helpful tip to make it all the more quiet.
After snapping the top into place on the canister take a measuring cup full of filter water from the old media and use that to pour into the intake tube. Do this until all air has been expelled from the canister through the intake tube. Tip the canister from side to side keeping the intake as the highest location so the the air will force it's way out leaving your canister fully "burped". Now just close both valves making sure the water is as full as you can manage in the intake side as air trapped under the cover will cause excess unneeded noise. This will also help seed your new media by restoring the bacteria to the "dirty" side of the system where it will be drawn into the new media to colonize. There's a simple fix to having to even do this if anyone there wants to email me for this simple redesign that would self evacuate all air from the canister. ;)

I hava had my magnum 350 for appx 18 years now and the only problem I have ever had was a bad o-ring on the lid. Simple to fix and it was just from multiple cleanings that the o-ring wore out. Note about every 7-8 years you should replace the impeller or if it becomes worn or noisy. If I had to buy another filter it would be the same thing! Hey why change it if it's already the best!

Rated 5 out of 5 by Moosewalk This product has longevity!
After using my first Magnum 350 for the past 15 years it finally quit after three power failures and a miserable winter. Due to the failures I lost my large Tiger Oscars and had to make a decision as to what to start over with. I decided to start a African Chiclid tank with a Brand New Magnum 350. Let's see if I can get another 15 years out of a reliable product. Thanks Marineland!

Rated 5 out of 5 by 8Milliongallons 165 gallon tank with a trio of 350s running for almost 2 decades
I don't get the "two days" set up either. Even my set-up, which was fairly complicated because I was running the discharge pf one filter into a roller filter for aeration, still only took about four hours total to set up. I've been running three of these guys for the last twenty years and about the only problem I've had has been the soft internal o-rings failing. But after two decades, what would you expect? The most challenging part of the Magnum 350 is deciding which filter media you want to use this month. Seriously, unless you're a complete idiot, this is probably the easiest system to set up. My recommendation - if you can afford it, get it. It'll last forever.
