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.
It does the job. I love the water sound but sometimes it has a humming noise. We have adjusted the unit many ways but can't seem to get it not to hum loudly.
Noisey when new quite after the wheels are not water repelant...
I've used these bio wheel units for years. The only "noise" I hear is the water trickling over the wheels. This can be considered a pleasant calming sound. You cannot hear the pump/motor itself.
Works for me 12/7/2013
I have always used the Aquaclear filters, 70 and 110, in my world they are the best. But, I just bought a used 56 gallon column tank with this filter on it. Right away I was going to replace it, but, when I used this and see how it keeps my tank crystal clear and that I can buy three of these for the price of one Aquaclear. DO THE MATH, LOL. I'm liking htis filter, and being on SS only, this fits my budget.
Filters great, but noisey overall 10/15/2013
Great at filtering, but noisey even when the water level is high. I replaced an older model 300 and that one was quieter than this new one.

Love this filter. The price is great and it keeps the water in my tank every clear. I have two and I am very pleased.
Very pleased 5/24/2013
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
Quiet and clean 10/24/2012

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.
Pretty Good 6/15/2012
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
too noisy 3/31/2012

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.
