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.

Rated 2 out of 5 by BriBri85 Penguin 200 - Too Noisy! Not the best fine particulate filtration
I have quickly learned that this filter is extremely LOUD! I have been running it for about a month now and at first it was just normally loud but last week the impeller started rattling. I took it apart and lubed it up with some petroleum jelly and that fixed it until my canister filter comes in the mail. But even with normal operation this filters motor and impeller make too much noise in my bedroom for my wife to sleep. Maybe fine if in your living room. It also disperses tiny bubbles constantly and slightly clouds the water. I have tried to adjust water height but that doesn't seem to work. I am still cycling my 29g tank and some cloudiness is expected but it doesn't seem to do a very good job with filtering the smaller particles which also are contributing to a cloudy tank and extreme Nitrite levels. I am now doing 50% water changes every day to keep my 5 Guppies alive and probably starving them slightly to keep from overfeeding. I am using conditioner and stability additives as well and I never wash anything under tap water. Anyways I think if your serious about your fish you should shell out the extra dough and get a quality, silent, canister filter.

Rated 4 out of 5 by IDK127 Found the fix for noise filter
While the filter is running, try to lift up the intake tube from the top. Just a little bit. Or when putting the intake tube in, don't push the tube all the way down.
