Rated 1 out of 5 by from Terrible products I bought my marineland penguin 200 a year ago, and one day we were woken up by a loud humming/rubbing noise when we found where the noise came from it was the pump and filter! I shut it off thinking some gunk probably broke lose( not sure how as I cleaned the stupid thing once a month) but the next day I took the thing apart to clean and remove what might be stuck and it was very clean and nothing was stuck!! What it sounds lie is the magnet on the fund is beating against the plastic insides where it sits I paid good money for this thing thinking I had bought a good product nope!!! I have bought Walmart one a few years ago and had to switch back to it and it is still working very quietly these marine land penguin series are terrible products!!

Rated 5 out of 5 by from Keeping fish healthy for years! I've had many aquariums in many sizes and have trusted my filtering to Penguin and the magic Bio Wheel for years and had to return big fishes to the store or get a bigger aquarium because since water condition is good they just keep growing !Now I moved and have a dmall mini penguin filter operating I cleat it with tap water and a ols tooh brush one or twice a year same time I change 50% of aquiarium water and it just keeps my fish happy.I do not find them noisy at all. Sometimes when water level goes down I hear a water cascade sound that actually helps me relax.

Rated 2 out of 5 by from Waaaaaay Too Loud At first the Bio Wheel was the item making the most noise, a scraping sound similar to when a fountain is low on water. I know it was the Bio Wheel because when I removed the wheel most of the noise stopped. The remaining noise was from the impeller that pumps the water. Over the past few days, the Bio Wheel is making a little less noise but the impeller has gotten louder. I've tried reseating the impeller and making sure the assembly was snug in its seat but it didn't help. The 'splash guard' over the Bio Wheel simply amplifies the noises. My old Penguin didn't make as much noise but somewhere down the line, the engineers or accountants lost sight of the customer's needs. The system does keep the tank clear but the noise can be heard (barely but heard) in the next room.

Rated 2 out of 5 by from Poor power filtering I live in an area where brownouts are common. I am now on my fourth filter in just over a year. It appears not a surge issue since the brand new surge protectors did not trip when the brownout occurred. This would most likely mean there is little to no protection filtering on the power input to the motor, of the pump, allowing for switching transients to damage the electronics. While I have otherwise been pleased with the performance of the filters, please resolve this issue so that I do not have to replace it 2-4 times a year, or look for more durable filter.

Rated 1 out of 5 by from Instantly broken I got the Penguin 350 a month or so ago and it now makes this insanely loud noise when its on and after a few minutes of doing that it just shuts off. I bought this filter because it was affordable for my price range and the reviews were good. I had it running for about 2 days then it started with its loud noise. I think it is the Impeller rubbing but not entirely sure. If there is anything I am doing wrong can you tell me because I set it up like the instructions given with the product and just plugged it in.

Rated 5 out of 5 by from Great filter for the price. I purchased this filter because I found it on amazon for cheap and it had pretty decent reviews. I have to say I'm not disappointed. I originally had it on my 30 gallon tank to over filter due to the amount of stock I had. I ended up upgrading tanks to a 65 gallon still using the same filter. I'm impressed. even though at this point this is putting this close to it's max tank load it is preforming very well. Crystal clear water.My only complaint it that is a little noisier that some hob filters I've used.Great product and I'd definitely recommend it to anyone.

Rated 3 out of 5 by from Was quiet at first... gradually getting louder 350B - was quiet at first... gradually getting louder, but I don't think it's worth the money to replace the impeller for this filter because it doesn't do any better of a job reducing NH3 NO3/NO2 than the much quieter canister filter I have on another tank. It was packed up for about a year and I can't find the bio wheels, which I also think are a bit too expensive considering I don't think they do much. Cartridges are easy to replace but expensive. Flow rate continues to be good. I will continue to use it until I run out of the filter cartridges then maybe sell it for $10. I would consider buying another Marineland filter because many people have had good luck with them, if it is on sale for a deep discount.

Rated 2 out of 5 by from Penguin Power Filter 350 I decided on this filter because all of the noise complaints on the 400, but guess what, I set it up, and the impeller is so loud I can hear it 3 rooms away! I'm not happy with this, it is actually so loud I can barely hear the water trickle that I really do like about this line of filters!

Rated 5 out of 5 by from Penguin Bio Wheel 350 I don't normally write reviews, but I felt it necessary to do one on this awesome Product. I purchased one and installed it on my slightly over stocked 20 gal fresh water tank. I did some modifications on the filter. I placed the two 'C' filters on one side of the filter, and in the other side, I put in a foam filter from a different company. On top of the foam, I added a bag of charcoal, and some filter glass wool. The gravel was dirty, so I stirred it up. The combination I used cleared to tank with in 45 minutes. I added some Spira Bio to start the biological filtration since it was a new filter. I checked the Ammonia, Nitrates, and Nitrites after two days. The count for all three were '0'. I am extremely happy with this filter and would recommend it to everyone!! PS..NO NOISE from the filter.

Rated 3 out of 5 by from Penguin 350 Great filter. Easy to maintain BUT, once the impeller begins to rattle, the cost to replace it , including shipping, was $10 less than buying a whole new filter. That did not impress me! Good but disposable I guess. I will compare other brands next time.

Rated 2 out of 5 by from penguin 350 It does the job of filtering ok for an HOB however I had to heavily modify this thing to make it quiet. This is the most noisy HOB I have ever used in terms of water noise. The design is deeply flawed. There are water chanel s on either side of the intake tube that make excessively loud water trickling sounds. I can hear it over my tv and it keeps me up at night. After I finaly figured out what was making all the water noise I had to stuff filter pad over the chanel and finally all I can hear is a light hum of the pump. So ad often as I have to do water and filter changes I will have to redo the filter mufflers and will be sure to tire of it quickly just to keep this thing quiet, I'll be sure to get sick of it and either go with a Fluval canister or Fluval HOB. I will never reccomend this filter or ever buy another one again.

Rated 1 out of 5 by from Never lasted longer than a month Tried the Penguin 100 on my 20L tank. First one never worked, second lasted about a month and then proceeded to just stop working and my third try gave out on me in about two weeks. While the filtration when working was excellent, I have never had so much of an issue with my filter's lifespan. I spoke with others on a facebook group I am in and the majority had experienced the same issue.

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.

As long as they move, that's all they have to do. There is no right or wrong speed. They can stop and start even, as long as they move on their own. To increase their movement, make sure the tank is filled to the top, and the impeller and motor are both very clean. BREX

We bought a 20 gal marineland kit over a month ago. The biowheel moves slowly and stops for a second or 2 and spins again. We just cleaned the intake tubes and tried replacing the filter cartridgue. Is this normal or should the wheel turn continuously

Asked by: Amysue
This is basically normal. It is simulating a wet/dry trickle filter. As long as it spins on its own, it is working properly, there is no recommended speed. Don't forget to clean the impeller and the motor as well since debris affects those the most. BREX

I have a 3gal tank with original bio-wheel. Last Monday I set it up and let it run, with out any fish, for 24 hrs. After which I added 1 Betta. Everything was fine until this evening (Thursday). There are now large bubbles in the water. Is this ok?

Asked by: Luvbettas
If you are seeing these bubbles on the surface, this could mean you are over feeding, and have a protein build up in the water. A betta should be fed 1-2 pieces of food, twice a day, and that is it. They do not need a lot of food, and over feeding is extremely bad for them. We would recommend changing about 10-20% of the water and putting some fresh water into the tank. This should be done about once a week with a tank of this size in any case. Add AquaSafe Plus and SafeStart Plus with the new water. BREX

Good morning - I have a Penguin Power Filter #75. The bio wheel is not spinning. We have set it up the same way as the video with come differences, our model does not have the two piece filter cover and we had to put the wheel together ourselves.

Asked by: DDBird
The Penguin 75 should have a one piece cover, not a two piece one. The bracket and bearings you do have to install yourself, and then you rest the bio wheel down into them. Make sure the water level in the tank is to the top of the tank, and that the filter cartridge is not clogged, etc. How well the bio wheel spins is dependent on the flow rate of the water through the filter.

my bio wheel spins unbalanced do I need to replace it

Asked by: fishy D
If it is able to spin on its own, no. Check your purple bearings and make sure they are installed properly and are clean. Also, you may want to take the filter apart and clean it as the flow rate of the filter is dependent on how clean the system is, and this directly affects the bio wheel. You especially want to clean the impeller and the filter box. BREX

What position should the “door” (grey switch) be in? There aren’t directions or any explanation for how it works. 

Asked by: Lbucklin10
You are referring to the mid-level strainer. This part allows more circulation of the water when it is in the open position. Unless you have small fry or tend to feed heavily and don't want the food removed, leave it in the open position. BREX

Instead of just using cartridges, try adding some bio media, such as bio balls, bio beads, ceramic rings, etc. The cartridges should be changed weekly when used in a salt water tank. Also, most nano tanks use a lot of live rock, which you didn't mention. BREX

I just bought a 200 b filter and there is a lot of noise. Sounds like the impeller. What can I do to fix this 

Asked by: Andy246
New filters can be noisy if air is trapped around the impeller. This usually lasts a day or so, max. To help reduce the noise, and ensure the impeller is not only okay, but seated properly, pull out the intake tube, impeller housing, and impeller, inspect them, and then re-seat them in the filter.

My Bio wheel is not moving on it's own but I can spin it freely. It worked perfectly one day and not at all the next. The water is flowing, the motor working fine but it just won't go. The wheel itself is is perfect shape. Any ideas on this are appreciate

Asked by: janeo
Make sure the water level in the tank is to the top of the tank. If it is low, this will keep the bio wheel from turning. If you have had it for a few weeks or months, the motor can be fine, but the impeller could be dirty and need cleaning. A dirty impeller slows the flow rate down drastically. You would need to pull the intake tube, impeller housing and impeller out. Clean each part and down in the filter box as well. Call 1-800-322-1266 is you need more help. BREX

Make sure you fill it up with water and that the tank is filled up to the top as well. If both are full, then remove the intake tube, impeller housing, and impeller. Clean the impeller, and clean out the bottom of the filter box, then re-install everything, put it on the tank, and fill it again. Call 1-800-322-1266 if you need more help. BREX

I have a BIO wheel 200 and it works but it very noisy. When it pumps. I have taken the impeller out and ck every thing nothing in the housing. I have to pry out the housing a little to quite it down but now that doesn't work. And less then a year old

Asked by: Driving me crazy
If the noise is a buzzing, make sure you plug it into a power strip with surge protection. Right now, heat sources are running like crazy because of the bitter cold, and this is putting a drain on voltage which can cause buzzing. If it is grinding, and you have sand, the sand has probably damaged it and you need a new impeller. If it is rattling, the impeller may be loose in the impeller housing. Did you also clean out the area at the bottom of the filter box where the impeller sits? Use a swab or twist a paper towel so you can pack it in there tightly and twist it to clean it out. Also, soak the impeller in distilled white vinegar in case you have hard water deposits. Please call 1-800-322-1266 so we can help troubleshoot it and see what you need. BREX

Penguin 350 making grinding noise. Cleaned impeller and tried vasonline still making noise. Going to buy new impeller. How do I keep bacteria on bio wheels alive since I am not running filter because of noise

Asked by: Dfeldbauer0427
The bio wheels have to stay wet, so float them in the tank. Do you have sand? If so, that's why the filter is noisy. Sand grains get caught in the bottom of the motor or up under the magnet, and wear grooves in the shaft or in the sides of the motor. You have to place filter floss in the bottom strainer or buy a sponge accessory to cover it. BREX

I have a H.O.T. Magnum Canister Filter and I'm going to add the Bio-Wheel to it. (Did not come together, although the instructions say WITH Bio-Pro System ) Anyway, I read something about not needing other bubble stones and the under gravel filter system

Asked by: betty246
Under gravel filters went out of popularity around 2000. Air stones are necessary in heavily stocked tanks or tall tanks. BREX

I have two penguin 300's from 1994. Yes, Yes, not 350's, the old school 300's with the media baskets behind the cartridge slot. My question after some googling is when did you stop making the 300's with those media baskets and replace them with 350's

Early 2000's. BREX

Asked by: Dustin757
A little soon for this to happen, but yes. Make sure the tank is filled to the top and check for any debris clogging the intake tube, filter box or impeller. BREX

My filter no longer is pumping any water nor is it making any sounds when plugged in. I have taken the intake tube out, the filter out, made sure there's no obstruction in the impeller, cleaned everything, and filled the filter box with water.

Asked by: TheScienceTeacher
Make sure you have the impeller in the filter box, by itself, no water, when you plug it in. If it still makes no sound, the motor is dead. If it does make sound, try soaking the impeller in vinegar and cleaning out the well of the motor with vinegar as well. If you are unable to resolve this, call 1-800-322-1266 as we would be happy to help. BREX

My power went out now my 350 will not propel water over the edge it makes a rattling noise. It does that when its about to go over normally but now it stops pushing the water thru

Asked by: Billium
This is a sign it needs to be taken apart and cleaned. Pay close attention to the impeller and the bottom of the motor, where the impeller resides. If you are unable to get it operating, call 1-800-322-1266. BREX
