Rated 5 out of 5 by from Description of Penguin 350 Filter I just received my Penguin 350 and hooked it up, and it runs great. It is quiet, which is amazing considering the large rate of water that flows through this filter. I wanted to let everyone know a little bit about this pump, since I couldn't find out too many details before I bought it. First of all, there are two filtration chambers, one on the left and one on the right. Each filter element consists of two squares of fibrous plastic material with what feels like activated carbon in between. They tell you to rinse them before installation, but very little dirt washes out when you do this.They recommend changing them every 2 weeks. Next, there is a single intake, which is a long tube that enters the impeller inlet in the center of the unit. The unit is self-priming: you just pour water into the filter box and turn it on; the impeller draws the air out of the inlet tube and starts the siphon automatically. From the center of the unit, the impeller pumps water into the left and right chambers, where it passes through a filter element and then spills under a "bio-wheel." Each bio-wheel is an inert, stiff plastic, corrugated cylinder, which forms a substrate for the growth of beneficial bacteria for removing certain metabolic by-products. The wheels spin fast and silently. The directions say that if too much bio-mass builds up, to rinse the excess off in chlorine-free water, but that they should never need to be replaced. After passing under/past a bio-wheel, the water descends down a chute on the inside of your aquarium. At the bottom of each chute, the water is deflected so that it mostly skims across the surface of the aquarium, away from the filter. This way, even though there is a strong flow, it doesn't produce a powerful current that the fish need to fight. The inlet tube also includes a mid-level intake, which is a set of holes a few inches below the top of the water that can be uncovered with a valve, to allow some of the water to enter from an upper level. If the valve is closed, all of the water is drawn into the filter from the bottom of the tube, which has a large strainer. Hope this helps! (And, yes, I am an engineer -- and proud of it!)

Rated 1 out of 5 by from Penguin 350 My only complaint with this filter system is the grinding noise from the impeller. I've taken the thing apart, rinsed, flushed etc. and it still makes the noise. The only way to get it to stop is by pulling the filter tube housing up some - this in turn slows down the filter flow going back into the tank. I'm very frustrated.

Rated 5 out of 5 by from Best hang on the back filters on the market! I have two Penguin 100 filters for a year and they are great! The water is always clear and I always get comments on how clear my water is from other aquarists. The only issue is, since one of these tanks is in my bedroom, if the water drops too low, there is a huge splashing noise. To combat this noise, weekly water changes keep my tank quiet.

Rated 2 out of 5 by from Quality with this product is inconsistant I'm currently very frustrated with my Penguin BIO-Wheel filter. I purchased a new 25 gallon tank about a month and a half ago and the Bio-Wheel 150 was included with the tank. Initially I was extremely impressed with this filter--the noise level was almost entirely silent, the option for two filter cartridges is very helpful for my goldfish, and the Bio-Wheel itself is great to have. Unfortunately, within 2 weeks of installing the filter it became quite noisy and began to sputter intermittently. I've tried everything I can think of--my water level is as high as it can be and has stayed that way since I first filled my tank. I thought maybe the aquarium sand in my tank had clogged the motor somehow, so I disassembled the machine very gently, rinsed everything off and re-installed it with no luck re-gaining my quiet filter. Today the filter is not even functioning at all. I don't know if I dislodged something important when I was cleaning it, or if my specific filter happens to be faulty, or what. But I'm so sad that something which ought to have lasted me years with the proper treatment has become dysfunctional after such a painfully short amount of time. Now I have to decide whether to trust this company and product again and hope I actually receive the quality that I'm paying for.

Rated 2 out of 5 by from Very noisy filters I purchased the Penguin 350 and 200 filters for my 60 gallon aquarium. Both of these filters are ridiculously loud, at night I can hear them from my bedroom, which is very annoying. I have replaced the impellers on both of the filters to see if that would solve the problem, but it did not. These are expensive filters and they are not worth the money, the much cheaper Top Fin filters that I have on my other aquarium are much much quieter. Also, the filters are not very compatible with the Marineand aquarium that I bought. The filter housing covering the Bio Wheels is jammed up against the light housing which has to be resolved by lifting the light housing off of its mount just to turn it off or on.

Rated 5 out of 5 by from Great Filter! I bought the 100B filter for my 10 gallon aquarium. In a short time of installing it my tank was more clear than it ever has! No problems with noise. The only problem I had was the intake tube was too long. I just cut the extension tube to shorten it. No big deal.

Rated 1 out of 5 by from Product Failed Customer Service No Answer I bought the Penguin 200 about 2 to 3 weeks ago. Did a water change filled the tank and filter and nothing. Unplugged the filter waited 5min plugged it back in and again nothing. I took the filter off the tank and inspected everything to which nothing seems wrong, except it wont turn on. I sent an email to Marineland explaining the situation and received no reply. This is a shame as I personally have always had great success using Marineland products while others advise not to. I now see why. Guess i will be buying a non Marineland LED for my tank. Sorry to say.

Rated 4 out of 5 by from Gets the job done. This filter pumps out water a lot, has decent filter cartridges, has the amazing biowheel, has a handy mid-level intake strainer, and can reach down far with the extension tube. Only reason I didn't give it 5 stars was because it is also a very noisy filter, so I don't recommend putting it in a tartan that is in your bedroom, but I do recommend it in general.

Rated 5 out of 5 by from 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 2 out of 5 by from 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.

Rated 1 out of 5 by from penguin 200 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 3 out of 5 by from Bio- Wheel Stinks I have a penguin 200 power filter. I have had it about 6-7 months. I had just a standered filter before. But I wanted to get something I thought would keep my tank cleaner. I liked the double filter cartridge system it offered and thought the bio wheel would be a big improvement. I change the cartridges about every 2 months and by themselves does a good job keeping my tank clean. The cost at my local Petsmart is about $10 for a 3 pack. But the bio-wheel is a joke. It worked the first month I had the filter then quit. Then after about a month just setting there it started working again for about a week. I went to my local pet store to try and get a replacement. But they said Marineland did not sell replacements due to patent rightsor something to that effect. So it just sets in the power filter doing nothing. It will spin for about a minute if I start it by hand. It has set not working for about 4 1/2 - 5 months. So if your looking for a bio filter look at something else. I believe this one is a waste of good money.

Rated 4 out of 5 by from 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 from 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 1 out of 5 by from Junk product From day 1 it has always been a little noisy, not crazy over the top, but noisy. My Tetra EX70 and Aqueon filters are dead silent. The fun started quickly, the impeller would randomly stall / jam, it would begin to make the most horrendous rattling noise my ears have ever heard, Cleaning the unit does no go, the whole product is just junk. I have a 30G tank that has a Chinese made / brand filter on it I got from ebay for $15 that has been running for 10 months, no jamming, no noise, just works. Why cant this product just work?

Rated 5 out of 5 by from 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 from 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.

I have a 38Gal Marineland bow front tank kit that came with the Penguin 200. I would like to increase filtration. What filter would you recommend or add, and is it necessary or good idea?

Asked by: JTInc
The more filtration, the better in most cases, but it is not exactly necessary, per se. That particular tank has a center brace, which means any filter you decide to use cannot be longer than 14". We do not have a larger power filter that will fit that space. You could go with a canister filter such as the Magniflow 220. BREX

Hi! I have a 10 gallon tank that is currently dealing with a power outage. The filter and biowheel stopped and dried out for 3 days now. Should I get a new biowheel once the power starts up again? I'm worried about starting from scratch.

Asked by: arianaa94
No, just do small partial water changes of the tank each day, like around a gallon or two. This will keep providing fresh oxygen to the tank and keep the biological filter alive until you have power again. Feed the fish very, very little, once a day. Float the bio wheel if you want to, but it will re-develop bacteria once it is going again. BREX

Make sure your water level is to the top of the tank and has not evaporated down. Lift the intake tube and re-seat it in case some debris has become lodged in it or in the impeller, and as a last resort, remove the intake tube, impeller housing and impeller, in case something got pulled in and is caught, reducing the flow rate of the filter.

I just got the biowheel 100 yesterday. Today I noticed it had too much suction. I adjusted the light gray piece on the filter. SNAP. Then... for an hour I tried to get the filter to work. The biowheel doesn't spin now. What is the problem?!

Asked by: Feisty_Unicorn
Well, first, there is no such thing as too much suction. When you closed the lever, you either slowed it down so much it can't pull enough water to turn the bio wheel correctly or you moved the intake tube slightly out of position so it is not operating properly now. Pull the intake tube, impeller housing, and impeller out of the filter box and inspect them. Re-insert them, and make sure the water in the tank is to the top.

I have Penguin 150 - I recently start to hear the motor noise was getting a bit loud. The filter seems to be working fine. I cleaned all the parts and the air stones are far from intake tubes. It is common to have some bit noise from the filter/motor?

Asked by: Question Lady
Noise occurs for a number of reasons. If this filter is a few years old, the impeller could be wearing out. If you only used water to clean it, try soaking the impeller in distilled white vinegar to remove deposits water cannot remove. Also, take a q tip and vinegar and swab the motor out thoroughly. Make sure there is no sand in the motor or up under the magnet. BREX

Asked by: MereR
Hi Mere! I'm sorry to hear it's not working. I suggest removing the filter cartridge, bio-wheel and other media first. Then fill the back of the filter to prime it. Plug it back in and continue to fill it with water from your take. It may take a minute, but the water should start pumping through normally.

Asked by: Mixcommunity
Purchase a new bio wheel and float it in the tank for a week, try to keep the old one in the filter system, even though it is not turning, there will be some bacteria on the portion that is in the water. Also, your biological filter is throughout the tank, so you should be fine, but monitor the water quality. If you start getting a spike in ammonia, do a small partial water change and add Marineland Freshwater Bio Spira or Tetra SafeStart Plus. BREX

Yes, it definitely will, as well a dirty impeller. Remove the impeller housing and impeller also, clean them, and use a paper towel or q tip down in the well of the motor. BREX

I'm starting a new tank with my old emperor filter I bought a while ago. Should I throw out the bio-wheel or should I wash it?

Asked by: Pøøh Bear
Neither, if it is in good shape and will turn. Otherwise, buy a new one. BREX

Is there a warranty on my mainland bio wheel filter? I have had it for under a year and it stopped working and is very hot. My old one that is over 10 years is working fine but I need 2. Thank you

Asked by: Gail G
It has a warranty of three years. However, hot means it is still working. Most likely the impeller is clogged and needs to be removed for maintenance. Take the filter off of the tank, remove this part and clean it, and the motor itself. BREX

I currently am using an AquaClear 50 in a 30 gallon tank. The filter is over 15 years old and fails to restart after a power outage. Am looking to buy a Penguin 200 as a replacement. Do these have the same issue of not restarting after loss of power?

Asked by: JBS from PA
Filters typically only have this issue when they need some cleaning or the impeller has become worn out. The Penguins will restart as long as they are not clogged with sludge, algae or other debris. BREX

Was the impeller housing already installed with the 200 model. I did not get those pieces if not. And my biowheel turned for maybe a couple of hours and then stopped 

Asked by: Rosario
Hi Rosario, Yes, we install the impeller and impeller housing here on the production line. Remove them from the right hand side of the filter box, and re-seat them in case they were pushed out of position during shipping. Also, your water level must be to the top of the tank. BREX

my penguin 75 will not suck up water to allow the wheel to turn what should i do?

Asked by: jen1992
We would recommend taking it apart to clean it. The impeller, down in the bottom on the right hand side, is probably clogged. Pull out the intake tube, then the impeller housing to access the impeller. Be sure to clean the bottom of the filter box as well. BREX
