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 can hear the motor running and can feel the sucking power from the intake tube but it is doing nothing. I returned it to the place of purchase and switched it out for another one of the same. I got home and installed it and again the same problem. I'm just gonna give up on this brand and return this last one and switch it out for another brand.

Rated 1 out of 5 by from Poorly made I purchased a Penguin Power filter 150 and I have had nothing but problems! The impeller is garbage! As soon as you take the filter apart to clean it, it is never the same.. It starts making a loud grinding noise that comes and goes and eventually just stays that way. I have cleaned this product with vinegar but it doesnt seem to help.

Rated 5 out of 5 by from Smmmmaaarrt Design! Mine has only been running 2 weeks, so long term reliability aside; the stacked cartridges, double adjustable inlet, & biowheel are awesome features. It's easy, quiet, & my fish favor the current on that side of the tank over the power head at the other (i'm gonna move it closer to the middle now). My 20gal salt cycled with 2 clowns, 8lbs of live rock, 10lbs live sand, & a bacteria dose in only 2 weeks!

Rated 5 out of 5 by from Excellent product Purchased 2 Penguin 330's in April 2013 for a 70gl and I am very happy with this product. Very quiet and no problems except for a slow bio wheel which is totally fine. These replaced 2 penguin 300's that were still running fine after 12 years straight service on the tank. and are now in the boxes as back ups. Crystal clean water as always and didn't even look at any other filter product line on the market before my purchase.

Rated 5 out of 5 by from Wicked Good Aquarium Filter and the product price is beyond fair! My last filter bit it when I came home to find at some point during the day my neighborhood had lost power. I have a very busy and somewhat hectic schedule and was only able to search for a replacement filter on line for short periods of time.Due to the fact the fish our my Son's goldfish, (dirty lil' buggers) I had to get a replacement ASAP as I do not have time to clean the tank a couple of times every 7-10 days.Within a few days I had narrowed down my choices to 3 different filters from 3 different competitors. Price, function and in store availability were my determining factors.With this information in hand, I headed out to the local pet supply store in search of a replacement filter.Once I had all 3 contenders in front of me for inspection, my choice was made easy by mainly the price of the filter, then the availability of replacement cartridges and lastly the fact that the particular filter I chose was the last one they had telling me I wasn't alone in thinking this filter is a good choice.So, I purchased the filter, brought it home, put it together, primed it and plugged it in.I had second thoughts as to my decision to not clean the tank prior to plugging in the new filter, but as I stated earlier my schedule is crazy busy and well, the tank was just a bit cloudy, not really dirty at all so I just left it be.When I woke up the next morning I was stunned at how amazing the tank appeared. It looks as though it had, had a thorough cleaning!!! The water is crystal clear and odorless and the fish, albeit are just your run of the mill goldfish are happy and thriving well. I am genuinely pleased with my choice of filter as are my Son's Goldfish!Given the price, availability and function, from here on out, I WILL only purchase Marineland products. THANK YOU for offering this filter and all the other products I've found in my search. Your products ROCK!!! :O)

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

Asked by: one666mom
Wow, poor fish! Pull the intake tube up and out of the filter body, then reach in and pull up the piece the tube came out of, the impeller housing. You may need to clean out the entire filter system. If you see hard water deposits, use white vinegar. Instructions for the Penguin 350, which you have, are on our site: BREX

After my power went out during Hurricane Harvey, I cleaned my filter and tube And re -plugged in the pump.  The impeller noise is horrific-  It is so loud! I have had this pump for several years and it has never been this loud.  Any ideas ?

Asked by: Lake girl
Make sure you primed it with water. Also, take a q tip or corner of a paper towel with some vinegar and clean out the motor region. Soak the impeller in white vinegar. You may have some deposits that are causing the impeller to rub something. Another possibility could be that it received damage from the power coming back on. We do sell replacement impellers, so you may need to replace it. BREX

How often to change the actual filter cartrage on filter once a month?

Asked by: Shownuff
Typically, once a month, but it will depend on your stocking level, how much you feed, and so forth. Sometimes it may be 2-3 weeks. In some cases, you can go longer than 4 weeks, but 4 is a good average. BREX

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

Asked by: NewFishMom
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.

Hi Angela71. To help prevent displacing your beneficial bacteria I suggest running the two filters at the same time or floating the seasoned bio-wheels in the water while the new filter runs. Either option should give the new filter a chance to season.

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. 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.

My 6 month old bio wheel stopped working, I have to penguin 200 for my 55 gal my community makes up 25 because of my 2 day old fry babies. I took the damaged wheel and put in the one that worked it didn't turn if I replace the unit will my frys die

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

I bought my Penquin 150 a few months ago and recently took it apart and cleaned the intake flushed out everything except I didn't use vinegar. I keep live plants in my freshwater aquarium, the intake clogs real easy will this stop bio wheel from turning?

Asked by: FancyLady
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
