Rated 3 out of 5 by from comparatively noisy, works pretty well in a different room with closed door. I bought a used 300 when I returned to aquariums from outdoor ponds. The biowheels were missing and the impeller shaft was quite worn and allowed the magnet spindle to bang around, but it was dirt cheap and worked well enough in conjunction with the under gravel system to keep the tank clean. When I decided to set up a second tank I bought a 200 and a 100. Both have covers that ratled from day one. The front covers over the wheels barely hang on and are frequently jostled off their mount points. Still, they also a decent job of keeping the tanks clean and the ammonia in check. After a few months it dawned on me that they were getting louder and I was hearing that mag spindle banging around in both. Sure enough both stainless shafts were worn, and it isn't due to gravel. Both tanks have 1/4 to 3/8 gravel, washed and sieved so that isn't getting in the moving parts on either pump.I've now switched to under tank cannisters.

Rated 5 out of 5 by from This product is queit and reliable! They back their product 100%! I bought a Penguin 350 Bio-Wheel. I have bought about a dozen Marineland Filters and have only had one issue. The issue was with a defective impeller. The pet store said I was out of luck since I could not find my receipt. I sent an email to Marineland customer service asking for help. The very next day I received an email from them. They are sending me a replacement impeller free of charge! I couldn't believe how helpful they were with my problem, and they responded so fast. This is why I always have and will continue to recommend this brand! Not only are the products easy to use and reliable, they back their products and will resolve any problems you may have. Thanks MarineLand. I am another very satisfied customer. I strongly suggest anyone looking for a quality aquatic filter to give this brand a try. There is no way you could regret it.

Rated 2 out of 5 by from issue with pump I set the 200 series up and it worked great. Then one day I added some more substrate to my tank. Halfway through adding the new substrate the gear mechanism started to make a strange noise at random intervals. I turned it off and checked the assembly to see that nothing had somehow become lodged within the impeller mechanism. I plugged it back in and after reassembling the unit and it continued to make the noise for a few more minutes. Then it shut off completely and I have yet to be able to revive it. I am curious if anyone else has ever experienced this and if so what did you do to get it to work again?

Rated 5 out of 5 by from Best HOB Filter I Have Ever Used! Excellent Customer Service. I have been an aquarium enthusiast for more than 30 years and the Penguin is the best HOB filter I have ever had. The Bio-Wheel offers the best biological filtration by providing the ability for both beneficial bacteria to grow on its surfaces, helping to lessen nitrate as well as ammonia and nitrite. Customer service is excellent as well. One of the rubber tips on my impeller stretched over a year's time and was not fitting properly. I contacted customer support to see if I could purchase just the tips and Laura Bradley contacted me in just a few days with an offer to mail me a new impeller at no cost. I am planning on setting up a larger tank ASAP (I really miss having a tank bigger than 20 gallons in the house) and have every intention of trying one of the Emperor HOB filters with it. I have been a fan of Marineland for many years and the Bio-Wheel technology ensures I will remain a fan for a long time; the customer service just sweetens the pot. :-)

Rated 1 out of 5 by from Loudest filter I have ever owned, regardless of the water level. I am sitting here months after purchasing this product listening to it splash water. How I've been able to maintain my sanity perplexes even me, as my aquarium is in my bedroom. From the moment I took it out of the box it was loud, but please keep in mind this is after I had to exchange it twice due to mechanical noise. When I heard no mechanical noise from this one I was thrilled, the splashing I chalked up to the biowheel not being broken in. Days passed, weeks passed, months passed, and it still makes significant splashing sounds. I purchased the 200 model because we have a 150 on the aquarium in the living room and it's very quiet, but sadly the 200 has done little more than grate on my nerves. I've adjusted the water level countless times to no avail, sure it provides adequate biological filtration, but I have no reason to believe that it is performing any better than any other (quieter) filter in existence. Early on I tried contacting the company, they assured me it was due to the biowheel not being broken in yet, confirming my suspicions. Sorry guys, I'm pretty sure it should be broken in by now. I'm just going to live with it this way and hope the splashing becomes comforting white noise. I would not recommend this filter. I feel kind of stupid for giving it as many chances as I did.

Rated 3 out of 5 by from Noisy Very noisy . Its not the waterflow but mechanical noise almost like a grinding i have tried playing with the intake tube to completely removing the propellar to make sure it was sitting in correctly. Nothing has helped. Unsure if im going to keep it or return it. It filters the water terrific would be a great product if not for the noise.

Rated 5 out of 5 by from does work! The Marineland filters work very well. I run my 55g saltwater with 2 emperor 400s. They do work! I have a Penguin 150 on my 2.5g pico reef tank. not only does it provide great filtration, it provides a lot of circulation in both tanks.The bio-wheels have never been an issue. The emperor spray bar needs to be cleaned about once per month to avoid clogging (old toothbrush works without disassembling it). and I have never seen my Penguin 150 stop.Noise is not really an issue. If the filter starts making some noise, its the impeller. Just tap on the intake siphon or wiggle it, and the noise goes away every time. I have only had to do that a couple times. Very quiet operation. I sleep with this thing running in my bedroom (6 feet from my head) and I am a very light sleeper.The back of these filters is great for many things. Not sure how much Marineland endorses modifying their product, so I won't go into detail. Suffice it to say that these filters are very versatile!I will recommend Marineland filters to anyone. My only advice is to use a filter that is at least twice the rated capacity. For example, if the Penguin 150 says it can work for 20 gallons, just ignore that. Get a Penguin 350 or an Emperor 400 for 20 gallons. Seriously. Its hard to over-filter a tank, but under-filtering is very easy.I made my friend buy a Marineland 20g kit. Awsome! Comes with a Penguin 150. That didn't cut the mustard. Put my spare Eperor 400 on it (yes, I have 3 Emperor 400s. and 2 Penguin 150s). Her freshwater tank is now very well circulated and the fish are much more active. (they seem happy, but freshwater fish are a bit harder to read)Just in case you missed that: GET FILTRATION AT LEAST TWICE THE ADVERTISED CAPACITY!!!!!Cant beat this value though. Great filters, low cost

Rated 1 out of 5 by from Noise, noise noise! I have 2 of the 350. I'll never buy Penguin again. I had Penguin almost 20yrs ago and it was awesome. What happened? I had a penguin almost 20 years ago that lasted for at least 10 years and it was fantastic. With the 2 that I have now it's nothing but trouble. Every time I shut them off to clean the tanks I fear they won't start again and they never do without me having to keep messing with it. Today the filter chewed the little rubber end off the empeller! I'll never buy another penguin. I want the company to succeed but you've got to change something.

Rated 2 out of 5 by from Penguin 200 is very noisy I've had a penguin 125 for many years, it runs quietly and works great. I currently use it as a secondary filter on my 29 gallon freshwater aquarium. My primary filter was a penguin 150 that became very noisy over the years and started making loud clicking sounds. I decided to replace it with a penguin 200 filter which I just installed a few days ago. The new filter makes even more motor noise than the last one. I will be taking it back to the store and purchasing a different filter.

Rated 5 out of 5 by from OMGoodness! I have a 55 gallon tank and use a 75 gallon Penguin filter. I'm on my 4th tank and refuse to use any other filter. There quite and reasonable priced. I do understand the trickling sound, but that comes from not having enough water in the tank. Once you refill the tank you don't hear it anymore. That's not really a big deal, it's part of the weekly maintenance. I'm upgrading my tank soon so i know I have to purchase a new filtration system ..

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.

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.

I just purchased a penguin bio wheel 75. As soon as a plus it in, it makes a loud humming sound, but is clearly receiving power. It will not suck up water though. I have taken it apart & put it back together. Am I doing something wrong or is it bad?

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. If it doesn't, try removing the impeller, cleaning it, then replacing it. We're happy to walk you through this over the phone at 1-800-526-0650.

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

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

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

Do I need to replace my Bio Wheel? Both of them stop spinning at times and I've noticed that there is a tear between 2 pleats on each of them. I've cleaned the filter as instructed and they are spinning slower than they used to.

Asked by: DebbieD
Spinning slower or stopping and starting are both okay, as long as they do turn on their own. There is nor right or wrong speed. However, if the tears are pretty large, we would recommend replacing them. Try to buy new ones, and float them for a week or so, then swap them with the old ones, in order to not disrupt your biological filter. BREX

Asked by: Char93
I just had to maintenance my Biowheel 100. Here is what I found. The impeller wasn't spinning and when I took the impeller shaft out and tried to spin it I found that there was much resistance to where it wasn't spinning freely at all. I took the rubber boots off the ends and using pliers, carefully pulled the plastic end off of one end to free the shaft. I took it loose and found the antennae of one of my dead ghost shrimp between the shaft and the plastic housing! I couldn't believe it but that kind of thing happens to me all the time. As soon as I put it back together it ran freely again and works perfectly. I hope that is of some use to you. If the impeller spins slowly, the volume of water will decrease in turn.

No, the flow is not adjustable. Your water level needs to be to the top of the tank, and the purple bearings should be in place at each end of the bio wheel. Make sure they are installed properly.

Hi Steve, It is recommended to place the strainer halfway to three quarters of the way down the back of the tank. Sounds like yours is in the ideal spot. BREX

I purchased a new 20 gallon starter kit with a 150 filter. I put everything together and plugged in the filter while the intake was properly submerged and with water in the reservoir. All it does is make noise and blow bubbles insise the unit. Help! 

Asked by: masimons47
The water level in the tank must be to the top of the tank. If it is, then pull up the intake tube and impeller housing, and re-seat them as they may not be properly installed. If you are unable to resolve this issue yourself, please call us at 1-800-322-1266. BREX

I just purchased a 10 gal tank and came with a 75 biowheel. Will the tanks be ok using a penguin 100?

Asked by: Kim85
Yes, the Penguin 100 is rated for tanks from 10-20 gallons. Make sure you only use the intake tube and the bottom strainer. The two middle pieces will only work if you have a 20 gallon tank. BREX

I'm curious if my marineland penguin 200 is defective? On random days & times it stops filtering/pushing water through the bio wheel. I have to lift covers off, (still water inside) lift the impeller housing a little, then it starts working again.

Asked by: Emilio
Hi Emilio, Do you have sand in the aquarium or an air stone near the intake tube? This issue usually happens when sand or bubbles get pulled up into the filter system. Move the air stone further away if that is the case. If it is sand, take the filter completely apart, and thoroughly clean it, then place filter floss inside the bottom strainer, or you can buy a sponge accessory at Petsmart to put over the strainer. If you have neither, then take the unit apart, and clean out the motor and the impeller as something may be interfering with it. Call us at 1-800-322-1266 if you are unable to resolve this on your own. BREX

I just bought the 10 gal aquarium starter kit and the 75 penguin was quiet but not good enough so I switch out to a 100 penguin and this one is louder than ever. I need help on any advice to get rid of the rattling sound please.

Asked by: Kkim85
Rattling is usually due to one of a couple of things: - air bubbles trapped around the impeller - pull the intake tube up and re-seat it several times to work the bubbles out - impeller, impeller housing or intake tube not seated properly - remove all of these, inspect them, and re-seat them - air stone near the intake tube - move it - hood pressing against the filter - check to make sure everything is fitting correctly Please call us for further assistance. 1-800-322-1266.

The 10 gallon starter kit came with a heater but it does not fit inside the lid. Maybe I didn't do it correctly but the water like ok the heater and the water level on the top of my aquarium do not match the heater is basically fully submerged into mytank

Asked by: Kkim85
All of our heaters require being fully submerged. They can be vertical or horizontal, and should be under water at all times. BREX

I run twin 350's hob filters on my 125gl aquarium. One of them bought from amazon doesnt sit on the tank correctly and now the bio wheels wont turn. It has been cleaned. Any suggestions out of the norm?

Asked by: Crp0069
The frame on the tank is probably too wide for this filter. However, you might check the stand off. This is a plastic piece on the filter body that holds it level against the tank. You will need to remove the filter from the tank to check on this part and make sure it is there and/or not damaged. BREX

Are bio wheels made of carbon?

Asked by: Koi56
Great question! The bio wheel is not made of carbon. The BIO-Wheel filter forms a large three-dimensional area for cultivating aerobic bacteria which work to eliminate toxic ammonia and nitrite from aquarium water. Read more about filtration here:
