Rated 1 out of 5 by from More trouble than it's worth. Bought myself a penguin 100 for Christmas and it died in less than 30 days. Just stopped pumping! Took it back to Petco and they gave me another one no questions asked. I was wise enough to keep my old bio wheel to put on the new filter and after about 3 weeks the wheel hardly turns. I guess I have to take the whole thing apart and clean or see if something is broken. I don't keep a lot of fish and I NEVER over feed so I'm disappointed that I have to do so much maintenance already. There has to be a better filter out there somewhere.

Rated 4 out of 5 by from Average Filter I purchased a 200 Penguin Bio-wheel filter 4 weeks ago.PROS:1. Good overall buy for the price.CONS:1. You can't have a dual filter cartridge as the packing says you can. If you add a second filter cartridge then the water struggles to get through both filters, backs up, and just pours out through the water overflow chamber. This completely bypasses the bio-wheel which defeats the purpose of having one. It started working property when I removed the second filter cartridge. But now after a few days it started backing up again. So I rinsed the cartridge and it started working again. Then a few days later it started backing up again and the cartridge wasn't even dirty. But again it started working after I pulled the cartridge out of the slot a little bit. I'm not sure what the problem is with the filters. Perhaps too full of carbon or perhaps the water overflow chamber needs to be bigger. Not sure.

Rated 1 out of 5 by from This product is not reliable I purchased the Penguin 200 Bio-Filter only two Months ago, and now it has started t fail. The problem seams to be that the flow of the water has been reduced to the point the Bio-Wheel will not turn. I have taken it apart to clean it, and it looks very clean, so something else is the problem. I certainly don't want to purchase another one, but will need a pump in the very near future. I don;t think I will get this brand again!

Rated 1 out of 5 by from lifespan of a mayfly My first penguin 200 filter lasted about 2 years. Not great, but okay for the price, so I bought another one. That one lasted 6 months. (The bio-wheel on both never turned, but I figured that was just a gimmick anyway.)I won't be giving this brand a third try.

Rated 1 out of 5 by from Noisy after 2 months When I bought this I was warned that many people had issues with impeller noise, but I got one anyway. The price was good and for two months it worked perfect. Then the noises started. I give my filters a good cleaning monthly and the inside is spotless, but for some reason it started making this awful rattling noise inside the impeller housing. You would think these things would last for more than a couple months. I understand that parts do wear out eventually, but that soon? And for the price of a new impeller, I could almost buy a whole new unit.I won't make the same mistake twice. Marineland should really step up the QA department drastically.

Rated 5 out of 5 by from High quality filter for freshwater tanks I ditched the water filter that came with my 20 gallon tank because it was too small, too loud and did a poor job cleaning my tank. I couldn't maintain a healthy tank. I picked up a Marineland Penguin filter because I recognized the brand and knew they made premium products. With the BIO wheel and high-grade carbon filter that comes with the Penguin, I've been able to keep a clean, clear water tank. The Penguin is much quieter than the filter it replaced. The water is sparkling clear and my fish have never been happier. I recommend using two filter cartridges--when possible. This keeps the water very clean and my fish happy.

Rated 1 out of 5 by from It was quiet, especially when it stopped working I bought this on May 28th to replace a filter system that we'd been using for several years that finally gave out. We had had one with a bio wheel in the past and our aquarium has an algae issue, so we went with the 200 for the 2 filters and the bio wheel. Up until today (Aug 7th), it's worked fine, but I came home from work and could hear the motor as soon as I walked in the door which is highly unusual. I walked over and took to the top cover off to make sure that something hadn't gotten sucked up into it and the whole thing just shut off and wouldn't come back on. I couldn't find anything clogging the tube or the fly wheel, it's like it just decided "Well, it's been 2 months, time to shut down".

Rated 1 out of 5 by from Nice while it lasts (which is not long) I had a Marineland Penguin 100 B filter, nice little gizmo, quiet, good filtration, mainly i bought because i liked the biowheel.I was satisfied overall with the product until it stopped working, approximately 9 months after i bought it. Since i had to buy another filter anyway, i decided to go with another brand as i did not see the value due to lack of durability.

Rated 5 out of 5 by from Great Little Filter! I really don't understand why so many people claim to have issues. I have been utilizing different Penguin models for many years on several nano reef tanks and have yet to have issues with any of them. I'm currently maintaining a 10 gal nano (Penguin 150B) which has been in operation for about 5 years and have yet needed to replace any parts aside from the filter pads. I wonder when the impeller is going to fail but it is still running fine. I highly recommend this line of Marineland filters.

Rated 5 out of 5 by from Great Filter Syatem Penguin 100 I am new to this hobby and i have a 10gl starter tank kit. I have never had a problem with this unit. great price and good size.Fish are loving it.I to did have that problem with my bio wheel but i cleand every thing inside and out and then cheanged the fileter and bio wheel and now works great. It seams the problem was with the bio wheel it was much heaver then the new one even when the new bio wheel was wet and used for 3 days. So what i am saying is if the bio wheel gets a lot of grouth on it it seams to slow down and can stop.And yeas sad to say i lost 3 guppies due to bio wheel stoping and not knowing what to do.Thanks to all at Marineland keep up the good work..

Rated 5 out of 5 by from Silent and powerful Penguin 200 Not sure why everyone is complaining about "noise" I know for a fact if you assemble the thing correctly you have no noise. This is true for ANY aquatic filter.Mostly what i read above sounds like a good 30% of them dont know how to take care of their fish.Lets hit the highlights of this filter:*Has a two part flip-top lidthis allows you to remove your filters and wash them off easily without spilling any water or making a mess.*The suction tube has TWO places to pull in debris,one mid way, and one at the bottom like normal*Excellent splash guard!Remember the dual flip-top lid i told you about? This makes a near 100% splash guard there isnt a drop on the side of my tank((Look at your filter doesn't it have white crusty stuff on it? This is from splashing a few drops now and then))*It uses TWO filter pads NOT side by side but back to backThis is just pure genius! Normal 50 gallon tank filters use two pads but place them side by side. But not marilands 50 gallon filterCONS:-Electrical cable is a bit too short for my taste-Water return is shot out through a small waterfall opening, which makes the water fall hard and fast. This might aggervate fish that are slow swimmers-Instructions were lacking just a bit they combined all 4 penguin models into one sheet of paper. the paper displays each model broken appart with arrows pointing to how everything goes. It gets the job done but i like to read about how each part works-The bio wheel is displayed in a fogged type clear plastic, for everyone to see how dirty the wheel gets when it has bacteria on it

Rated 2 out of 5 by from Short life span I have had this for about 6 months. It has been filtering rather well which is why it has two stars. For some reason the bio Wheel just stopped turning and no one can tell me why. I tryed cleaning it several times and nothing helped, and now it seems to be getting louder. Piece of junk.

Rated 4 out of 5 by from Very good, Not noisy just adjust this.. I like this filter. I have a 55 gallon aquarium it does a good job. I am thinking about getting a different filter now because of a new algae breakout.I had this filter for a while and it was quiet. I was giving it a thorough cleaning one evening and put it all back together and fired it up. It was VERY noisy. I figured the magnetic motor was messed up, so I kept adjusting it. I found MY noise issue to be the light gray piece (looks like a tab sticking out) on the shaft needed to move to cover the "vent" on the tube.I posted this review to hopefully help people with this issue because it was driving my wife and I crazy.The filter is a good filter, but I am looking into getting the emperor series for an upgrade.

Rated 5 out of 5 by from ONE OF THE GREATEST FILTERS EVER MADE! I have tried a lot of filters on my tanks. Most of them filtered okay, but there was still that fish tank smell. These filters take away all those odors and keep the water so clear! They are nice and quiet too. I also like the fact that they feel well made and are reliable. I don't know much about the Bio-wheels but they must work because I have never had an ammonia or nitirite problem. I own 4 of these filters and when I get a bigger tank I am going with Marineland! A great investment!

Rated 5 out of 5 by from 150's & 350's I don't get it. Where do people get noise from with these filters. I purchased 2 350's and 2 150's and they are very quiet. My older ones produce the water trickling sound but no other impeller sounds. I am recently back in the hobby and have purchased 6 Emperors 4 pengiuns and have just ordered 4 more 350's. One thought I have on noise is if people are getting sand substrate in the filter which will ruin an impeller in no time. One other thing is if the carbon filled cartridges are not rinsed to remove the small particles, which will also destroy the impeller causing noise. I came close to ordering a different brand of filter because of a good deal but backed out before I put in the order. I started thinking about my old Penguins that my son has that are still running and have been for many many years. The price of these on line is like stealing and they're better than most all other filters out there.Sorry for the long rant but i hate to see a great filter beat up on. One more thing my experince on filtration is at least 8 x tank size.(30 gal = 240 gph filter) for healthy fish.Thanks Bob

Rated 2 out of 5 by from Decent filtration, loud impeller I have had the Penguin 200 in my 30gal. freshwater tank for about 6 months or so and I will say the water does stay reasonably clean even with the large number of fish I have. The down side to this filter though is that the impeller makes a TON of noise. I have tried various ways to quiet the noise, but it will not stop. My last resort is to buy a new impeller and see if that solves anything. I personally wouldn't recommend this filter because the price does not match the quality and the noise is very irritating especially at night while I'm trying to sleep.

Rated 5 out of 5 by from Great product - Penguin Bio-Wheel 200 I don't know why other reviewers have a problem with their Bio-Wheel 200 being noisy. I set mine up according to instructions and it's worked fine with very little noise. I installed a second filter in the slot closest to the Bio-Wheel and noticed that it was obstructing the wheel. Then, I realized that I'd put it in backward. I turned it around, re-installed it the RIGHT way and again, works perfectly and quietly. I would recommend it to anyone!

Rated 4 out of 5 by from I think the reviewers are using this product incorrectly... Since my boyfriend has moved in with me, he's made me add 8 fish, 2 cats, and a second chinchilla to my family. I had an Aquaclear 30 filter that was given to me with a 29gal aquarium, and he just wasn't satisfied with it (I saw no problem, but I guess that's how hobbyists are.) He suggested we get the Penguin 150 filter, and now I can see what he was talking about. We only use one filter slot at a time, and it gets disgusting!! Sadly, the filter cartridges are expensive. I try to rinse them out to prolong their life at least a few days, but it normally doesn't work. I'm going to have to look online for cheaper filters. However, the filter is silent! I don't understand all these negative reviews concerning the sound. The only time this filter gets loud is if the water level is too low (especially if the slits in the tube are above water) or if there is air trapped in the filter somewhere. The solution: Pour some water into it and make sure the tube is securely attached how it's supposed to be. (Meaning: just mess around with it for a few moments and you should have no problem.) However, for a while our biowheel would not spin even when there was adequate water flowing under the wheel. Out of the blue the wheel started to spin again and has been spinning like a champ ever since.In conclusion:Pros: works well, silentCons: expensive filters, wheel sometimes doesn't workPS: why is my nickname "punky" and it had some weird email already typed????

Rated 2 out of 5 by from It's just OK. This filter is just OK. If I were to do an HOB filter again I would go with the Emperor 400. I have the Penguin 350 and I'm just so-so with it. It seems flimsy when I clean it and I prefer the additional filter area of the 400. Wouldn't buy this one again.

Rated 2 out of 5 by from I would expect to be blending margaritas with something so noisy For the past 9 months this filter has done a great job keeping my 35 gallon tank clean. For this reason alone I have given this product a second star, but cant rank the filter as "average" due to the insanely short life span of the impeller.

Rated 1 out of 5 by from RIDICULOUSLY LOUD....Short life, BIO-Wheel 200 RIDICULOUSLY LOUD. I have used Marineland filters for 4years but no more. I have been through 2 bio-wheel 200s in about 1.5 years. They both started out quiet but slowly started to sound like they are chewing through gravel. I have tried cleaning the impeller housing but it was a waste of time. This filter does it's job but I would expect it to last longer and not sound like a rock tumbler.Also, the impeller it's self looks like it is corroding...... Why can't you buy just the impeller I'm not paying for the entire "assembly".

Rated 5 out of 5 by from Penguin 150 is a great filter I have never had the noise problem with mine. But the water fall effect dose show up a little faster due to the outlet being a little shorter the aqueon's in my 75 gallon. Not big deal, just keep the tank full. Recovers faster than the aqueon's after tank cleaning. Over all im very pleased.

Rated 2 out of 5 by from PENGUIN 150 VERY LOUD Seems to be a problem with these filters. I have 2 of them, one is okay but after a few weeks the impeller bacame very loud in the second one. Everything I have tried ( cleaning, repositioning impeller and impeller housing and lift tube) has not helped. It does drive you crazy after awile.

Rated 5 out of 5 by from Best outside filter I have used. I currently use two of the 200s. They are very quiet and effective. The only negatives are that the flow rate can not be adjusted (minor issue) and that is not a refillable carbon element available. I would prefer a separate foam filter and separate refillable carbon cage or bag.

My Penguin 350 seems to be working great on a 55 gal freshwater tank!  Does the adjustment on the intake snorkel speed up or impede the flow when it's fully closed?

Asked by: AtlFish
Neither, really. It is there to allow water to be pulled in from the middle of the tank, and not just at the bottom of it. This is most important in taller tanks, as it moves the water at both levels, but it has no effect on the actual flow rate of the filter. BREX

Can I / should I rinse the bio filter wheel (I have 2 Marineland 350 for almost 2 years and all is good). I noticed few small packets on the wheel that looks as remaining of food, is it okay to rinse under cold water or will it hurt the bacteria? Thanks

Asked by: AviW
It is best to simply use a q tip and swab between the folds rather than rinse the bio wheel. Some people "swish" it gently in water taken from the aquarium during a water change. Do not rinse with cold, chlorinated water though. BREX

Does the bio wheel spin at a rapid spin or just slow and spin

Asked by: jackie01
When you first install the filter, it will spin pretty rapidly. Once it absorbs water, it will begin slowing down, and once it builds up a really good bio load, it may actually start and stop. There is no right or wrong speed. Slower is generally better just because the bio wheel is exposed to oxygen for longer periods of time, leading to more biological filtration. BREX

Hi, my Marineland Penguin bio wheel 75 has not worked. It has been off and on, and my 4 year old fish are at risk. They are rare fish. Anyway, any suggestions on how to get it working? Tried starting again, unplugging, cleaning it. PLEASE help. Thx.

Asked by: JacieBoo
If it is starting and stopping so to speak, make sure you do not have sand in the aquarium that could be causing the issue. When sand is in use, you need to place filter floss inside the strainer or put an accessory sponge over the strainer. Another thing that will cause filters to turn on and off are air bubbles. If you have an air stone in the tank, try turning it off and testing the filter. Take the filter apart, removing the intake tube, impeller housing, and impeller. Clean it thoroughly, especially the impeller, and the bottom of the filter box, where the impeller resides in the motor well. You may have some sludge or other build up causing an issue. In the event of hard water or marine water, use distilled white vinegar to clean everything and rinse well. Last, make sure it is plugged into a power strip and not an outlet in case of voltage issues, if this is an older home. A filter's purpose is not to keep the fish alive, but to reduce the maintenance of the tank. So until you determine what the issue is with the filter, step up on the water changes. Vacuum and do 10% at a time, every couple of days, if the filter continues to have an issue. Also, call us directly so we may assist you. 1-800-322-1266. BREX

Asked by: Arux584
The only type of filter that would be safe for fry and baby shrimp would be a sponge filter, operated by an air pump. If you use the Penguin filter, place filter floss inside the strainers. This comes in bags for just a few dollars and looks like a giant cotton ball. BREX

How come my wheel has stopped spinning and what can I do about it??

Asked by: teens
It is completely controlled by the flow rate of the filter. Most likely you need to take the filter system off of the tank, and take it apart to clean it. Pay close attention to the impeller and the reservoir it sits in. Use hot water and distilled white vinegar to clean it. BREX

An up to 20gal filter on a tiny 2 gal is way to much suction I suggest looking into Nano tank filters for 5gal or less 5gal being the most suction on your tiny tank if your working with Beta they don't prefer to much water movement as there not strong swimmers but a filter is a must i think tetra and Fulval make nano filters

I own two marineland filters. The 100 and 200 series. I love them both as they are very quiet and work amazing. However I just picked up the 350 for my 55gallon tank and it seems to make a lot of noise. Mainly the motor. Is this common for the larger size

Asked by: Jwhite
No, not really. It should be just as quiet. Remove the intake tube, impeller housing, and impeller and re-connect then re-seat them. These parts may not have been installed correctly on the production line or may have been knocked out of position during shipping. Also, make sure there is no air stone near the intake tube, and that the filter is plugged into a power strip with surge protection.

Asked by: Olga G
No, if the goldfish are good size, they will not be bothered by this filter at all. The additional filtration would be good to have, but make sure you run the old filter for a week or so as well, until the new one has built up its own bacterial base. Or you can put your old media into the new filter system. BREX

I have the Marineland Bio Wheel Penguin 200 bout it maybe 2 months ago. Wheel stops spinning, water overflows the intake chute. Like the cartidge is stopping the water from flowing. Have taken it all apart and rinsed and cleaned any buildup.

Asked by: Eliza87
Take it apart again, this time place the impeller into a dish of distilled white vinegar and let it soak for about 15 minutes. Take a paper towel and soak a corner in the vinegar, as well, then twist it and pack it into the motor at the bottom of the filter box. Let it sit for a few minutes, then twist it around to clean out the motor. You may also want to use a small baby bottle brush to clean out the intake tube and the impeller housing. There is some debris somewhere, interfering with the filter. BREX

I have a penguin bio-wheel 200 and the wheel is still spinning but the water is not getting clean, what should i put inside the filter?

Asked by: AwesomeRazor
There are a lot of possible reasons why your tank may not appear clean. It would help to know more about the tank such as how long it has been set up, what kind and quantity of fish, your routine for partial water changes, etc. We would actually recommend a partial water change, addition of Tetra SafeStart Plus, and either a second filter cartridge or adding some additional carbon, ammo chips, floss or bio beads. Test your water quality parameters as well to help determine the issue so you can make an educated guess as to what type of media you need to add more of to the tank. BREX

My filter is brand new , plugged it in and nothing is happening 

Asked by: Ivy1
Pull out the intake tube, impeller housing, and impeller, check them for any damage, then re-seat them. The impeller may be jammed or not seated properly. If the unit still makes no noise, contact us at 1-800-322-1266. BREX

I have a 350 that I bought at least 20 years ago still rocking and rolling. My question is do y'all have reusable cartridges like the company that walmart sells? All i can ever remember seeing are the completely sealed filters.

Asked by: Insaneinnixa
We still have the sealed cartridges, but you can buy media containers for this filter and fill them with whatever type of media you want/need for your tank. Here is a link to a site that carries them. Scroll to the bottom of the list on this page: BREX

my 10 Gallon bio wheel filter isn't working. I've tried priming, un plugging it and plugin it back it...... could there be a loose part I should be concerned about?.....or anything else I could do?

Asked by: CFred44
A very dirty filter cartridge can slow the water flow and stop the bio-wheel from spinning. Try replacing the cartridge.

Hi I has a penguin 200 with my 29 gallon tank and the bio wheel has stopped turning and the water started to over flow over the intake tube I put two new filters in on 01/22 and my tank is clear and clean so I think its to soon to need new filters ?

Asked by: Coco
Hi Coco, How often you need to change filter cartridges depends on the size tank, number of fish, types of fish, and feeding routine. Typically, they need changing every two to four weeks. You may also need to clean out the intake tube, impeller, and well down inside the filter box. These areas can build up sludge, algae, and other deposits. Take the filter apart, and clean each piece separately. BREX

Is there any Carbon in the actual bio-wheel? I know the filter inserts have carbon, and I'm not using them intentionally. But something is removing the medication from my quarantine tank and I suspect carbon in the bio wheel.

Asked by: maggarcj
No, there is absolutely NO carbon in the bio wheel. BREX
