Did my research and people couldnt tell the difference from the Emperor 400. So i bought this since it's price tag was way cheaper than the 400. Ive been running this for about 2 months on my 75 gallon tank. I have an Oscar and they're messy eaters and leave particles in the water from some certain types of foods. The particles dissapear after 20 minutes due to the power filter's water gallon suction ratio. I completely love how silent it is. You need to fill the tank up to at least the waterfall lips of the filter so you wont hear the water splashing. Good good stuff here.
I have a 55 gallon community tank with angels, pleco's, clown loaches, and cory cats. Some messy fish, but this filter carries the load. My only recommendation is to clean the intake tube with each water change. It gets pretty gunked up, very easily.

I think this is an ok filter, it definitely does its job of providing chemical and mechanical filtration, but heres a tip.
I do ALOT of work with fish tanks and supplies. One thing I have noticed from cleaning, fixing and modifying aquarium supplies is that in the last few years, maybe a little longer, marineland has started using cheaper parts.
I have an older model of this filter and it has adjustable flow and a bit better construction. I liked it, so I bought a new one. The newer one is noticeably cheaper in construction and components, no flow control knob and after four months it periodically grinds and it is LOUD! I hear it across my decent sized home.
So bottom line, it does its job as a filter, and in my opinion its a great filter. Just has a few things it could improve on.

I have had my Penguin 200 with the bio-wheel for about a month now. Before I bought it, I did some research and read the reviews about this particular model. I saw all the bad press people were giving it about it's "restart problems" and "Bad Connections" etc. etc. and I have to say, the only problem with the P-200 are the short-bus riders who don't have their water ALL THE WAY UP TO THE BOTTOM OF THE OUTPUT AREA.
5*s*t*a*r*s, the bio-wheel is super, it isn't noisy (you know it's on, but it doesn't stop you from reading a book), and my fish have personally told me that they love it. My fish talk to me.

The best I have ever used . I have two 30gl. African Cichlid set-ups that I keep over crowded to cut down on the fighting for territory and a 30 gal . community tank and these filters do a great job with the bio-load of each . The bio-wheels do a great job of polishing the water , and a great place to grow good bacteria, this is why they slow down after they been used for awhile , the Bio-wheels build up bacteria and muck , simply rinse them off in dechlorinated water that is the same temp. as your tank water so you do not kill off the bacteria and they will continue to serve you well . Easy to change filters , which I change only one at a time so as not to remove all the bacteria in my filters . And even after my own laziness of going weeks without cleaning it , it will run smooth and whisper quiet . I have never had a problem with noise on any of my 3 Penguin 350 filters , after a water change or power outage just a little shot of water in it to prime it and it starts right up just as quiet as before , and sometimes that is not even needed as the water that was left in it will prime it for me . I will never use any other filter .

Since I purchased these sponge filters for my tanks, my aquatic pets are much healthier. the tanks stay cleaner and they are so easy to clean plus very economical to use. I keep all kinds of tropical fish, axolotyls and crabs. I have tried other companies sponge filters and they do not compare in keeping the tank clean and healthy. They are also much quieter than the other brands even though they put out large bubbles; the current is not bothersome to my creatures that do not like rapid moving water. The Como Biochemical Sponge Filter for Aquarium Fish Tank are the only sponge filters I will buy.
