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.

(was bought for me) This particular one runs to loud & i don't know why. To my eyes nothings bent, magnet surface is smooth. Propeller seated as well. Its like an obnoxious hum & buzz.. huh I like the idea of these things. but it would be nice if they weren't so dang loud. Lets see how good you guys customer service is.

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.

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)

I have a Marineland 75G tank and I want to use two Penguin 350 filters. The filter doesn't fit on the frame, though, which is odd since I'm using all Marineland products. It doesn't sit all the way down and it makes it lean forward. Any advice?

Asked by: LCLCola
It's definitely a Marineland tank. I bought the LED AQUARIUM 75 & STAND set from PetSmart. I have purchased everything I own for the tank from Marineland except the gravel, driftwood, and the fish themselves (I'd probably get those too if you all sold them). I can see the sticker sticking out a bit but it is obscured by the center brace of the stand. To be more clear, the Penguin 350 will hang on to the frame but the frame on the 75 is a bit thicker than the 29 Gallon I used to have it mounted on, so it doesn't sit completely on the frame. If you sit one on a smaller aquarium and then on the frame of the 75, you'll see what I mean.

My bio wheel doesn't turn unless I cover the overflow outlet. I've cleaned all the parts, what else can I do?

Asked by: Jknt
I'm not sure I understand what you mean by covering the overflow outlet, as that should not effect it. If you only used water to clean, soak the impeller in distilled white vinegar, and clean out the bottom of the filter box, specifically the motor well, with vinegar and a paper towel. You may have deposits interfering with the flow rate that only vinegar can remove. Also, make sure your purple bearings are in place at each end of the bio wheel.

I bought a Biowheel 350 and from the beginning it is very noisy. Not "splashy", it's a very loud mechanical sound. The aquarium is right in the middle of our house and can be heard from every room. I don't remember this happening the last time I owned one

Asked by: MrsG
We are sorry to hear you are having some noise issues. Remove the intake tube, impeller housing and impeller. Inspect all of them, and clean any debris off that you find. Also, check down in the well of the motor where the impeller resides to make sure there is no grit or sand, any debris in that area. When inspecting the impeller, make sure it was connected to the impeller housing properly. The blades should not rub the underside of the housing, for example. This would definitely cause a mechanical sound. If you cannot resolve this, please call us at 1-800-322-1255. BREX

We have the 350 and it does not work. Any suggestions on what to do?

Asked by: Tolly
Hi Tolly, That depends on what you mean by "it won't work" as well as how old it is at this time. If it is brand new, pull up the intake tube, and remove the impeller housing and impeller, then re-seat them. They could be in the wrong position. Also, prime it by filling it with water, and make sure the water level in the tank is to the top of the tank. If this is an older filter, the same basically applies, except you need to clean the parts, especially the impeller and the well of the motor. Please call us if you cannot resolve it. 1-800-322-1266.

Purchased a penguin 350 a friend, all parts dirty/nasty. I have been told I don't need to replace the bio wheel, but should sterilize by soaking in bleach/water mix for 30min, rinse, & dry. Is this correct?

Asked by: KJZ1
Hi KJZ1, We would recommend cleaning the plastic parts with a distilled white vinegar and hot water mix then rinsing well with hot water alone. As for the bio wheel, as long as it is intact, and will spin, you should not need to do anything. Everything living on it will dry up and die off. BREX

Right out of the box it isn't working. I followed the directions to the t, but it isn't working. The motor is going but it isn't sucking up the water. I pulled apart the housing for the wheel and it rotates fine.

Asked by: halle
Hi Halle, Make sure the tank is filled to the top, and you have primed the filter with water. Re-seat the impeller, impeller housing and intake tube. If one of these is not seated correctly, it won't prime. If your water level is really low, it won't prime, and if there is no water in the filter, it will not prime.

Asked by: Mama
Hi Pesche, Yes, the bio wheel should turn on its own. It may stop and start, that is fine, but it should not stay stopped. Here are some things to check: - make sure the purple tabs are in place at each end of the bio wheel, and are seated properly and clean - pull out the intake tube, impeller housing, and impeller, clean the impeller and filter box, flow is important - check the cover and make sure it is not pressing down too hard on the bio wheel, it may need a minor adjustment Let us know if you need any additional assistance.

my dad got the family a fish tank, he and I put it together successfully, but we are wondering what the grey lever does/ is for on the Bio-Wheel filter for our tank. please help.

Asked by: little tom tom
The gray lever allows you to pull water in from the middle of the tank, and not just from the bottom of the tank. This increases circulation, and allows for more water movement, especially in taller tanks. Whether you leave the lever open or closed is totally up to you and does not effect the filter. BREX

I recently bought marineland 20G tank comes with penguin power filter, after a week running the filter I started to notice significant amount of micro bubbles all over my tank. Is this due to the filter?

Asked by: sarors
Most likely it is due to a low water level in the tank. The water level should be to the bottom of the top frame, otherwise, water spilling down from any filter will create more bubbles. BREX

If you are not hearing any noise at all, not even some vibration, the motor was probably damaged during a power surge.

My bio wheels are squeaking when they rotate; is this typical and is there a solution to stop the squeaking? Thank you for any help! 

Asked by: SullivanL
I think my wheels were squeaking due to the tank not being level; the wheels slowly move to the right side of the filter. The plastic side of the wheel rubs against the side of the wheel housing making the squeaking noise. I plan to perfectly level the tank which should solve the problem.

My bio-wheel 350 won't balance right on the rim of my tank ultimately causing water to come out the back of filter. Is there a part to make it balance again? 

Asked by: Koiman
You should have what is called a stand off on the front of the filter box. If you pull out your Quick Set Up Guide and look at the Penguin 100 in the first box, look at Part 11 which is the filter box. In the middle of it you will see a piece that sticks out. Your 350 has this also, or should, but it is not pictured in the QSUG. This is not sold separately so you would need an entirely new filter or could fold a piece of cardboard to take its place for now. Please call us at 1-800-322-1266 if you need further assistance.

Asked by: Juls
It sounds like it needs cleaning, Juls. Most likely it has pulled something into the impeller or motor region. Unplug the unit, remove it from the tank, pour out the water and remove the intake tube, impeller housing, and media. Inspect and clean each piece separately, using hot water, white vinegar, and a soft cloth. Also, make sure the water level in the tank is to the top of the tank, right below the top black frame.

Can I add two 150 bio filters to my 20 gallon tank?

Asked by: ProfDomo
That is going to depend on what type of top you have on it, and what type of fish are housed in it. The first affects whether they will fit or not. The latter may or may not be able to handle the flow rate. That's a lot of flow for a 20 gallon tank. BREX

I have the penguin 400, it pumps water through filters, I have cleaned it out. When it starts up water flows out the tubes for biofilters but once it gets going to full water flow the tubes for biofilters stops and they no longer spin??

Asked by: Skeezerk
All the pieces are there, it pumps out the spray bar until the pump get to full capacity, this is when it quits spraying out bars and only through filters. Spray bars are not clogged, worked great until about 2 weeks ago, now biofilters just spin a little here and there do to flow from filters

I have a marineland penguin 350 bio wheel. Have had no issues but my question is this. Is it alright to use four filters at one time?

Asked by: Fishlady47
Yes, indeed, it is! This is the reason for the way the filter box is designed. It allows you to add additional media, in the form of four cartridges, or two cartridges and two media containers (sold separately). BREX

Will 30 gal filter work on a 40-55 gallon octagon tank whats the possibility that it will

Asked by: tiger1
It will work on it, but will not clean it properly. You would need two of them or need to do water changes more frequently. BREX

I recently set up a 65 gallon freshwater tank, using Marineland power filter 350. How often should I change the filters? How do I clean the wheels?

Asked by: EllenG
Cartridges will last 3-4 weeks. The bio wheels you do not clean unless they stop, which is rare. Then take a q tip and clean between each fold. BREX
