Marineland Penguin Power Filter, 200B - 30 to 50 gal - 200 GPH

I have a 55gal tank...my other 2 pumps broke because the water was low for too long and I needed a quick replacement and (with just the one pump) it works perfectly. I've had it for about a month now and it is very quiet and works great!! Very pleased considering it was so cheap!!!!

The filter works well and is fairly quiet.

Wonderful filter at a WONDERFUL price. I have a 37 gallon tank, and it works great. Pretty quiet. No Issues and I've been using it for almost 3 months now.

I haven't installed this filter yet, but I bought it to replace one just like it. The one I have like this one lasted about 7 years. I find the bio-wheel very efficient in providing effective filtration, and I'm satisfied with this filter's performance.

it's a good filter but I was looking for a great one. Also it's very very noisy and a in many ways mostly where the water comes back into the tank.....

I like the design of this power filter and LOVE the fact that the roller filter never has to be replaced.....just only cleaned with warm water. This filter is the perfect size for my 32-gallon fish tank. What I don't like about it is the fact that it's a little noisier than the one I had of a different brand. It almost sounds like a waterfall, so if you like the sound of running water, then you will love this product.

Purchased recently and in use about a week. Seems to work alright however the bio wheel did not work from the start . In checking other reviews it seems I am not the only one with a bio wheel issue . Seems to be more common than it should be. If the bio wheel was to be a real selling point for these filters the wheel should be more reliable than what seems to be the case. Since the wheel does not work properly seems to work like any other filter of same size and capacity. Just sharing my experience in case you are thinking of this filter because of the wheel.

This is a high quality power filter and it is more solidly built than the Aquaclear filter that it replaced. It is noticeably more noisy than my beloved Tetra Whisper 4 filter that finally died after 20+ years of reliable service. Still, the noise isn't terrible and the fish seem healthy and happy.

CANCELED my filter and never even told me!

This is the worst filter ever! Gets super noisy, I only have a 20 gallon with one South American cichlid, I keeps acting up! I have to unplug it wait then plug back on now not even 90 days later its dead! Ridiculous I did my homework these penguins are supposed to be great! The front wheel always in a stopped position ridiculous! Ive hade tanks over 20 hrs never dealt with this!
