Rated 1 out of 5 by from Noisy, Stopped Working Have had a few months. A month in we started having problems with it. We had to take it apart and wash it and adjust it on a weekly basis. Now it's making a horrible noise. I'm up to fixing it daily. Why have a product that has to be adjusted on a daily basis?

Rated 3 out of 5 by from Noisey Bought this about 2 mos ago and it has been noisey all the time - I've tried to buy another filter ( canister ) but the fish guy says I've got the best , sometimes I can move the propeller housing up and down and get it to stop but most of the time it's very noisey and my oscar absolutely hates it and gets annoyed by the constant noise

Rated 5 out of 5 by from Works like a charm! Ive had a 200 for three years and it came used at that! The other day our electric went out for 10 seconds and then NOTHING! Tried what "I" knew and to no avail. I wrote in to you guys and didnt know how to get to the impeller. ORDERED a new one online and my husband with a hair knotted impeller. So thanks for your great help and in such a timely manner. Everything is working again perfectly. I just didnt know how to get to that impeller. Thanks so much again. I have never had a problem with this filter and it is quiet and does the job. I just didnt do my part.

Rated 5 out of 5 by from Have Multiples I currently am running a Penguin 100 and two Penguin 350's on two different tanks, and I must say I absolutely love them. They do a great job at keeping my water sparkling clean, and clear. Very low maintenance, very sleek looking, and very quiet. I recommend these filters to everyone.

Rated 4 out of 5 by from SECOND CHANCE Well I've only had my penguin 200 for a little under two months and the pump burned out. Talked to the warranty department and they took care off me without any problems and said they will swap the old one out as long as I send the bad one back. filter works great when it works and very pleased how my situation was handled

Rated 3 out of 5 by from Loud I have a penguin 350 that I bought from a friend for my 38g. It was making a lot of noise that sounded like it was coming from the impeller so I replaced the impeller, impeller housing and the intake tube hoping all that would help and it did. The filter was almost completely silent for about 5 hours, then it started making the noise again. I don't know if it's just the filter going bad or if I got a bad part but the filter isn't very old. Maybe 6 months. Disappointing

Rated 5 out of 5 by from Penguin 200 I watched many utube videos about hob filters. Though the penguin models were not the most highly recommended I liked the bio wheel. Very happy with my 200 and I don't care what anyone says. That spinning bio wheel is just cool. The penguin works very well paired with my 220 canister filter also from marineland on my 55. Keep up the good work

Rated 5 out of 5 by from Great customer service I have always used these filters and never had an issue. Bought a penquin 250 two months ago, and it was a little noisier then all the other filters. Took it all part for its monthly cleaning and realized the propeller blade was cracked and hanging loose. Called the c.s. line asking if I could purchase just the part, and they offered to ship me one, no charge. That's great customer service, not only does that make me want to continue using their products, it shows they would prefer to keep the customer happy and support their product....great job guys and thank you

Rated 5 out of 5 by from Great filter I bought the Marineland Penquin 150 Power Filter about a month ago. Loved it from the start! Nice and quiet motor, if the water level gets low enough the water flow can be somewhat loud but it doesn't bother me. Sounds like a tiny waterfall which fine. The only complaint I have with this product, is the lack of directions. I have had a few questions regarding the filter and the directions are very limited.

Rated 5 out of 5 by from Penguin 350 AMAZING I made the mistake of going with Aqueon filters on my 5 tanks . I had been struggling with Clarity n poor water conditions. Even running large filters on small tanks. Finally I bought 350 and in ONE DAY cleared my tank . Shocking how clear water was. There is absolutely NO competition for Marineland in power filters!!. I am saving up and can't wait for the day I have a house full of Marineland products!!

Rated 5 out of 5 by from Lots of reasons to use this filter! I have had a penguin 200 in my 30 gallon tank for about 3 weeks. The filter has good water flow, and very little noise. I purchased the Penguin after comparing to other HOB filters for several reasons:1) The bio wheel allows replacement of filter media without risk of crashing the nitrogen cycle.2) The filter accommodates 2 filter cartridges, allowing customization of filter media of various types.3) Marineland offers a re-fillable filter cartridge which can be opened and filled with bulk activated carbon, or my choice of chemical filtration media. I am able to cut mechanical filter media (such as 50 micron felt) and place between the two cartridges to produce great water polishing.5) The bio wheel seems to me to provide a media for biological filtration on par with drip or wet/dry filters.It is worth noting that my filter did not pump water when I received it from Amazon. Marineland cooperated by sending a new impeller, which I received promptly, and which corrected the problem. While it is not pleasant to purchase a product which does not work, I am willing to accept the fact that problems occasionally occur even by the most careful manufacturers, and I have no reason to think that Marineland was especially negligent. To the contrary, customer service was fast, efficient, and courteous regarding my problem.Finally, it would appear that many of the negative reviews posted here and elsewhere regarding these filters seem to be posted by users who neglect to read the product's instructions, or follow recommended maintenance. I am puzzled by reviews claiming that the filter makes excessive noise; mine is quite silent.This is the first Penguin I have purchased, and would recommend this product.

Rated 1 out of 5 by from Awful!!! 0 stars I have a penguin 350 for almost 2 years now. I paid around $45 for it. I've had to replace the impeller assembly 14 times already. These impellers cost around $20 a piece with shipping! It should cost about $2 as often as it needs to be replaced. What a terrible design by Marineland! These filters are absolute garbage! I will never buy another filter from them.

Rated 5 out of 5 by from Great filter! I have had a 200 for about 6 months now and could not be happier. The fact that it has 2 slots for filters is great for when it's time to change the filter. Simply rinse an install the new filter in front of the old filter and a week later the new filter has built up enough bacteria to remove the old filter without lose of cycle. Get idea and the bio-wheel is always keeping your bacteria active. I only wish my intake tube was a little longer. It sits about 5" above my sand substrate and I wish it was adjustable so I could get it closer to my sand. Other than that great product and very affordable!!!

Rated 4 out of 5 by from Real good but room for Improvements. First let me say I think the bio wheel concept is the best idea out there and I have over 55 years experience in aquariums. However, the best way to mount these filters is to hang the suction pipe inside the stand pipe of an under gravel filter. The benefits are too many to list here. However, filters above a size 200 the suction pipe wont fit into the vertical stand pipes. Also, older filters had round suction pipes making it easier to fit them into the vertical stand pipes. The rectangular suctions for size 200 and down can be manipulated.

Rated 3 out of 5 by from Not great for 38 gallon bow front I'm sure fir a smaller tank the bio wheel 200 would be a good fit, but after using it fir a mobth in my 38 gallon bow front kit, I could not get the tank to cycle or really filter, just seems to much tank or height for the 200. Aftwr much research and lots of money on filters I opted for the internal canister. Decided to keep the 200 firbio media only, and withjn 12 hours the tank was prestine. If your loominv for a filter with better media options the bio wheels are not it.

Rated 5 out of 5 by from Reliable Filter. No Mishaps =] I have had every freshwater filtration device on the market. The bio wheel penguin series is by far the most competent filter. Also to clear this out immediately, since I'm raving about this product, I can say that I have no monetary ties with any marineland or any other aquarium product, and never have. but this company- Marineland -simply created the best filters on the planet. Had a 20 gallon reg and a 20 long for 8 years....always had problems with cloudiness and disease until switching to the bio wheel penguin series (and a ton of water changes naturally). After my 20 gallons were long gone when I went to college and I fell out of the hobby, I got my first paycheck after graduating and bought a basic 10 gallon starter kit just to get myself back into the great hobby. Everything in the kit was great but I had to add the penguin 100 series filter to the tank and I have yet to have any problems with the tank. Pair any Penguin Series Marineland filter with keeping up on your tank cleanings: and you'll always have serene water quality within your aquarium. Thanks again guys ! (and again no one paid me to write this review as you can see I have the grammar of a 6 year old donkey.) lol Happy New Year!!

Rated 5 out of 5 by from Great HOB Filter Never had a problem with either my Penguin 100, or 350! Had my 100 for my 20Gal for almost three years and it still works like a charm. It is very quite and does great in removing waste and debris from the water. Every month I take it apart and clean it in a bucket of water from the tank. Just started a 55Gal goldfish tank a few weeks ago with the 350 and it works awesome. It is also very quiet. The only sound is all the water being pushed out from both sides of the filter. Will stick with Marineland filters!

Rated 5 out of 5 by from Penguin 330- Longevity! Love this filter. I have been running this double bio-wheel filter for over 7 years without fail. We are surly not aquarium experts and use in a 55 gallon hobby tank that has had its share of algae blooms, poor water and filter change intervals, etc. this filter keeps on going and most of our common tropicals live over 5 years (we currently have a 7 yo Mollie !). Filter changes clear any cloudy water right up. I feel for the people who have trouble out of the box but for us this filter has been like a tank. (We have replaced the impeller once )

Rated 5 out of 5 by from Best filter after trying tetra and fluval owner of advanced tanks since i was 10. For 55 gal. tanks tetra filter doesnt seem to last for more than a couple years. fluval didnt handle biowaste load like it should have. Have had marineland penguin C for 9 years now. Even with an overloaded tank (temporary foster situation) it worked fine. If maintained and filters changed it's the best filter.

Rated 2 out of 5 by from Really poor design. I recently bought the Penguin 200 filter to pump my turtle tank because my old one broke. Almost immediately after installing the filter a jarring blender like sound was emitted by the pump. I thought something was wrong with the impeller, so I removed it. Upon removing it I found that nothing was wrong with the impeller but in fact the mid-level intake strainer does not create a tight enough seal to allow the filter to even pump the water. The only solution is to seal the holes on the filter or to by a separate extension adapter for the tube. Why the filter doesn't already come with one of these extension tubes to remove the need for the the broken mid-level piece is beyond me, and the whole product seems like a trick to get you to spend extra money to get it to work.

Rated 1 out of 5 by from Never even worked. I recently bought this filter (200) for my new 45 gallon tank. I began setting it up. It took me a while to figure out which direction to put the filter cartridge, as there are no actual instructions or anything mentioning, in detail, on how to assemble the product. Once I figured this out, I added water to the back, and plugged it in. It immediately began making a very loud noise, which I figured was the impeller. I figured that the noise might happen, as most of the filters I have purchased make a loud grinding noise for a short time before any water comes out, but 5 minutes later, there was still no water flow. I unplugged the filter, and dissembled the impeller housing. I tried again, to no avail. I tried for another half an hour before deciding to go onto the internet and see if anyone else had the same problem, or to see if there was a solution not mentioned in the "Instructions." I still don't have a solution. I would like to give a higher overall rating, but this is all I can do for now.

Rated 1 out of 5 by from Broken right out of the box Just got this filter and the impeller makes a rattling noise right out of the box. Inspected it and tried a little Vaseline to quiet the noise but no luck. Having the shaft go up and down is causing the noise. Terrible design and I'll be returning it.

Pull out the impeller and impeller housing as well as the intake tube. Make sure you have the filter filled up with water too, and then re-seat these parts. The tube should fit pretty snugly. If you still cannot get it to operate, call 1-800-526-0650. BREX

I purchased two Penguin Power Filters(up to 20 gallon) from amazon on 7/5/2018. My order number is 113-0996277-4789857. The bio wheel not/harder spin. Why?

Asked by: Yunqi
Make sure the water level in the tank is all the way up to the top of the tank, as water level affects the filter flow which in turn affects the bio wheel. Remove the impeller, and clean it, as well as the motor in case of debris, and check to be sure the bio wheel bearings are properly in place, and clean. BREX

my bio wheel is not turning I looked and seen it has a 2 inch rip in the paper part is that why its not turning should I replace

Asked by: keesha1994
Yes, that is probably why it isn't turning, although you may also want to clean the impeller and motor as well. The bio wheel is directly affected by the water flow rate, so if the filter has a build up of sludge, algae or other deposits, this could be the issue. BREX

My penguin 150 has algae in it. It’s in a 33 gal w Neon, Platy, Loach, shrimp, and 2 dwarf Plecos. There is no algae visible in the tank, water is clear. It’s been cycled for 1yr. I feed 1x / day and regular maintenance. What should I do? Thanks.

Asked by: Grad
Your filter requires maintenance periodically, just like the tank, or your car. Every 2 or 3 months, you take it off, take it apart, and clean all of the various parts, other than the bio wheel. Use warm water, an aquarium wire brush, soft cloth, and if you need to, white vinegar. BREX

My emperor is not pulling water through the biowheel spray bar. It is three months old. I’ve cleaned the intake, propellor, and spray bars with the pipe cleaners provided to no avail. The filter is noisy and send extra bubbles into the tank. Thoughts? Thx

Asked by: nlee
The only thing that causes water to not move through the spray bar is a missing flow manifold housing cover, or one that is down in the motor but not snapped onto the bottom of the flow manifold housing. Extra bubbles makes me wonder if the water level in the tank is low or if there is an air stone near the filter. BREX

My Marineland 350 Penguin Power Filter just suddenly stopped workin. The day I added in PH-raising substrate, so now my tank is extremely dusty. The filter came with the marineland 55 gallon kit, is there any way some sort of warranty covers this?

Asked by: RanusH
Have you tried cleaning it out? In most cases, it just needs to have the impeller, impeller housing, and intake tube removed and cleaned. You also need to clean out the motor. I would guess that the pH powder clogged the impeller and caused it to stop turning. Warranty is 3 years on manufacturing defects, you would need to call 1-800-322-1266 for the address, and other information. Receipt would be necessary as well. BREX

You would need a mid-level strainer and an extension to lengthen it. It will be fine with one additional one of each of these, but may not be powerful enough for two additional extensions. BREX

New to keeping fish and can't figure how I'm suppose to adjust the water adjuster on the intake tube. i.e if I want to filter the water on the bottom of the tank do I close the upper part of it?

Asked by: c1jackie
You can leave it open or close it, depending on your needs. It helps to increase circulation of the water through the tank, and closing it will definitely pull more water from the bottom of the tank. BREX

Asked by: bookjunkie
Make sure you have cleaned out the intake tube as well. Also, wipe between each of the folds of the bio wheels in case some of the Eco Complete has clogged it. Easiest way is with a q tip. And last, make sure to wipe off the purple bearings at each end of the bio wheels. BREX

We have a Penguin 350 that we've had less than a month. One biowheel now doesn't turn most of the time. Both turned at first. It is only one and it doesn't matter which side it's on. The other works on either side. What could be the problem?

Asked by: stonewolf
The first thing to check is to make sure something isn't clogged. Take out the intake tube, impeller housing, and impeller and clean them. Also, check down in the motor. Make sure the water level is to the top of the tank where it should be. If the bio wheel still won't turn after all this, check the purple tabs it rests in and make sure both are properly in place and smooth. If it still won't turn, call 1-800-322-1266, it may have become damaged/warped somehow. BREX

At first, it worked efficiently. However, noise started developing and the biowheel stopped spinning. Smudge forms on the filter cartridge within a day. It's also noisy, because I keep the water a few inches low, to protect my nerite snails. Suggestions?

Asked by: ioinva
Several. One is to raise the water level where it should be, below the rim of the tank. You can drop it a bit, maybe an inch, but any hang on the back filter will make loud water noises if the water has to drop several inches, so you will need to adapt if you want to continue with it low. Low levels also affect the flow rate of such filters, reducing them, and making it harder for bio wheels to turn. The noise issue along with the bio wheel stopping are probably due to something caught in the impeller. You need to take the intake tube, impeller housing and impeller out and inspect/clean them. You may also need to clean out the motor in case of gravel, sand, grit, plant matter, etc. The recommendation for cleaning any filter is once every 1-2 months, depending on the tank size, inhabitants, and so forth.

My penguin bio wheel 200 filter is less than 3weeks old . It continues to go into over flow with 2 days of putting a new cartridge I'm on my 4th cartridge in less than 3weeks . What is the problem with these filters oh an I already returned 1 penguin bio

Asked by: electricman
If it is overflowing, then your tank may simply be dirty, and the cartridge is clogging rapidly, trying to remove the detritus from your tank. In that event, you should vacuum your gravel well, and change out 25% of the water to help balance the tank. If the tank is not that dirty, then you may have pulled some type of debris into the intake tube or the impeller, impeller housing or motor. We would recommend in this case to take the filter apart to find the offending debris/detritus. Cartridges have an average lasting time of at least 2-4 weeks in properly stocked and maintained tanks.

On the tube going into the tank that sucks the water up, what is the adjustment for

Asked by: un13lucky
The mid-level strainer allows you to adjust the flow rate of the filter. BREX

I just installed a 29 gal. marineland aquarium with the biowheel and it is pushing water out with lots of power and that normal? It's like turbo power!! Kind of noisy too but hopefully it'll calm down over time is what I read.

Asked by: hbheel
That's normal, and yes, it does calm down. To speed the process up, float the bio wheel for a day or two. It will absorb water more quickly, which weights it down, and reduces that noise and splashing. BREX

After a power surge, or a brief power interruption, by pump hums but does not restart filtering. Also the bio wheels never turn and have not since we got the system about 2 years ago. We have moved to a new location with the same problems.

Asked by: Mary53
Have you taken the system apart and cleaned everything? We would recommend soaking the impeller in distilled white vinegar, and swabbing out the motor with vinegar as well. All of the problems you describe are usually caused by a clogged filter system or low water level in the tank. The water level must be to the top of the tank. Last, but not least, check for the purple bearings at either end of the biowheels. If these are missing, the bio wheels cannot turn. They will also need cleaning. BREX

I moved my tank into a new apartment and not my filter is plugged in but not working AT all please help

Asked by: Schmidt
Sorry to hear that Schmidt! Have you removed the intake tube, impeller housing and impeller, cleaned all of these parts and the bottom of the filter box really well? If not, you may have build up or debris that is causing the issue. You can use white vinegar to clean all of them if you see white buildup anywhere on the filter, as this is a sign of hard water. Vinegar will remove it. Soak the impeller itself for about 10 min in the vinegar and clean out the motor well with vinegar as well. BREX

My Penguin 200 is cycling water, but the wheel doesn't spin? and there is hardly any visible dirt on the cartridges when I remove them. But the tank is still dirty? It's only a year old and cycling a 36 gallon tank with live plants and large fish.

Asked by: jess713
If the tank is cycling, there may not be a lot for it to mechanically pull out, but you need biological filtration. Make sure your water level is to the top of the tank as the bio wheels are directly affected by the flow of the water. Also, pull out the intake tube, impeller and impeller housing and make sure there isn't some plant matter or other debris clogging any of them or the motor. Also, if you have large fish, and there are several of them, you may need additional filtration or a larger tank. Cycling a new tank will also look dirty as you can have a bacterial bloom. BREX
