Rated 5 out of 5 by Fishgirl703 Product does its job
I wrote a previous review for the filter media, but it probably belongs here lol Anyways, the filter is really good. I'm impressed with it and have tried other filters and was not satisfied. While it might be more expensive then other filters, it's def worth the money. It makes my 10 gal look super clean. And the bio wheel is really a big help b/c that means i won't have to add any beneficial bacterial supplement ever again. Will warn you though, bio wheel may stop spinning but thats fine because water still runs threw the bacterial supplement that is on the bio wheel. You can replace if you want but it would be a waste of money and there wouldn't be any supplement on the new bio wheel.

Rated 4 out of 5 by BTracker Ok, a bit noisy
Daughter bought a Marineland 20 gallon starter kit. Very nice kit for the money. But the impeller is a bit noisy. It was set up today we will wait a and see for a week if the noise goes away.

Rated 2 out of 5 by JayDragon Good filter, but SO LOUD
I don't know how the people in other reviews got lucky enough to not have noisy filters, but I nearly cried for the first 24 hours I had my 100. You could hear the thing across my house, on a different floor! I looked up the problem online and found many other people with a similar problem and found that some were able to solve the issue by lubricating the inpellar with Stress Coat and making sure to place it back into its place completely straight. I did this with no luck. Thank goodness my father is incredibly handy and was able to use a thin razor blade to shave off a teeny tiny bit around where the inpellar is inserted so that it could no longer hit the sides as it spins. This fixed the problem, but I don't think I should have to do minor surgery to make a filter run without excessive noise, voiding the warranty in the process. I'm happy with how the filter runs now, but my goodness, I don't think I'll ever purchase this filter again.

Not pleased at ALL. I purchased on for my 30 gallon tank and followed instructions to a T and when I went to plug it in , nothing happened and itssmelled burnt so I returned it for an exact product and the impeller on that one would run for 30-45 mins and then shut off , I'd have to adjust it and it would kick back on. Today I purchaseed a new tetra brand filter and would like my money back for this penguin filter.

Rated 4 out of 5 by BillC Impeller worn out
Two years ago I purchased a Penguin 350B HOB power filter. The filter has worked flawlessly until about two months ago. At that time the impeller began to make a rattling noise. After receiving a new impeller I carefully examined the new and old impeller. While holding each impeller by the two rubber bushings in one hand and spinning the impeller with the other hand I could definitely feel a slight wobble in the old impeller while the new one spun very smoothly. I carefully examined the metal shaft of the old impeller with a micrometer. There was no apparent wear in the shaft therefore obviously the plastic piece which contains the magnet and fins had worn to some extent and was causing the rattle. I replaced the old impeller with the new one and the pump was again very quiet. I am writing this review to caution owners of the Penguin and Emperor models HOB filters that as part of normal maintenance the impeller may begin rattling after 2 or 3 years and require replacement. As a side point after searching many sites on the internet I determined that the lowest cost for the Penguin 350B impeller was (believe it or not) the manufacture, Marineland at $11.97. Most mail order suppliers were between $15 and $20.

Rated 4 out of 5 by allnicknamesiwanttaken Functions as intended 95% of time
Purchased a Penguin 350 under the duress of another brand's failure. Function very well except at times, one or more of the biofilters stop spinning and must have either the shafts cleaned or the part where the shaft rides in the housing cleaned or both. Regardless of filter brands, it is never a perfect world. I wish they would provide/develop a pre-filter screen to trap larger "stuff" before filter. However, if I was in the filter business, I would want the consumer to buy new filters (ie: ink jet cartridges). Never the less, a system of washable pre filter screen(s) would be nice. May just buy new filters rather than wash dirty ones to manage cost.

Rated 5 out of 5 by Fishlover123 Beautiful filter
I have a 50 gallon aquarium and recently just purchased this filter. My old filter was a millenium 3000 and it was starting to die. This filter is quite and it is easy to maintain. Ever sense I purchased this it has made the water crystal clear and it is and is safe for my live plants. The mechanical filtration is eliminating all of the debris and dust from the water and the bio wheel is working because my tank has never looked this healthy and clean before. This has to be one of the best filters that marineland makes.
