The Marineland Penguin 350 Power Filter features complete 3-stage aquarium filtration to keep your aquarium clear, clean, and healthy. The patented Marineland bio-wheel system provides oxygenated surface area for nitrifying bacteria, which keeps your aquarium totally free of harmful ammonia and nitrites. High flow rates maintain optimum water circulation and ensure proper bio-wheel rotation. The adjustable mid-level intake strainer allows you to take aquarium water from mid-tank for complete circulation.
The Penguin 350 cover design and sealed motor reduces water noise while maintaining optimum oxygenation. The Penguin model 350 uses the handy Rite-Size C filtration media cartridges so choosing the correct replacement media is simple. Penguin filter cartridges take care of all mechanical and chemical filtration in your aquarium and are extremely easy to replace. For complete, easy aquarium filtration for your aquarium, nothing works like a Penguin filter. The Penguin 350 is rated for aquariums up to 75 gallons, and has a maximum flow rate of 350 gph.
Cheaper to buy a new filter from you than to replace 2 wheels OTC. Worth the money. Can be very loud water level drops. Clear water maker.
very loud 4/8/2013
I have many different filters over the years. I have used this one for over a year. It isn't as loud when the water level is kept up high, but it is the noisiest filtration system I have ever owned. It is a pain to clean too. I would never buy this brand again and can't wait until this one dies so I can replace it.
Quick Shipping - Great Price

I've had dozens of filters over the years. I've never replaced its impeller and its easy to disassemble and clean. Easily the quietest if used properly.
This is NOT quite. Just put it in and I am looking at replacing it with something else.
This is NOT quite. Just set it up last week and already am thinking on replacing it with something else.
Pretty Good 6/15/2012
This filter clears up water very good and will only be too loud if water level is low. Only complaint is that its hard to clean, but overall a good buy.

Only complaints are its a little hard to clean and you need to change filter cartridges often. Overall, cleans water nicely, quiet, and a good buy.
This filter is real good compared to the others i have purchased. It will only be noicy if u have water below the the suction tube. other than that a real good filter

On the box it says quiet operation but it is the worst noise maker I have ever had, not happy at all with this product.
