I bought a used aquarium for my classroom. It came with a Marineland filter system. When it wore out over Christmas break the water and sides of the aquarium were very green. I replaced the filter with the same type because I had extra filter replacements for it. After a little scrubbing on the glass I put on the new filter and the water was clean within a day, and has been clean ever since.

Filter worked for a grand total of 3 days in a 30g. After that it would consistently stop running every 8-12 hrs. It would overheat and the motor would stop. I could feel the heat through the body of the filter from where it was overheating. I had to disassemble, allow to cool, fiddle with the turbine then it would run again for another 8-12 hours. Had much higher expectations from a marineland product. Ended up replacing with a store bought internal canister. I do not suggest this product.

I bought this filter to replace my Marineland Emperor 280 which I've had for over 12 years and had been discontinued. This filter works well if you don't mind a noisy filter. The filter itself isn't noisy, it's the overflow after it goes by the Bio-Wheel and it hits the water. It sounds like you have a mini waterfall in your living room. That's where the noise is located. It's so loud that I have to turn the tv up quite a bit to listen to it! Aside from the noisy overflow, the filter works rather well on my 33 gallon bowfront tank. I was surprised to see it work as quick as it did when first placed on the tank. I really want to say that it works as well as my old Emperor 280 and I thought that the 280 was the best filter I have ever owned! There is NO adjustment knob for the angle of the water (Jets) hitting the Bio-Wheel. I really think that this missing feature is what's causing the filter to be so noisy! Other than the noise, the Penguin 200 is a pretty good filter...now if I can only figure out how to stop the noise...lol. I hope this helps... Stay safe... Rico Read full review
