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 )

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 5 out of 5 by from Very quiet after new impeller Shortly after I bought my filter system, the bio wheel stopped spinning. It would work on and off so I figured I just wasn't cleaning it as frequently as I should or didn't have the water level high enough. But then there was a horrible grinding noise that only got worse after a thorough cleaning. I called the company and the gentleman was happy to help; after a couple questions he decided to send me a new impeller. I received it in just a few days and now the filter is quiet a mouse. I am not only happy with the product but the customer service as well. As a side note, I very much wish that customers would troubleshoot and call the company to get help before leaving such negative reviews. It skews prospective customers' decision making when shopping for a filter system.

Couldn't be happier. Step it up marineland.

Rated 2 out of 5 by from 10 Gal Kit - says 100 Filter but actuallly got 75 I purchased this in 2015 and set it up. There is a small BIO Wheel bit it doesn't turn when the lid is on the filter. I have tried to re-position the lid and the wheel, but the only way it does work is when I put something under the lid to hold it up so that the wheel can turn freely. Has anyone else run into this problem? And why does the box say 100 when it is actually a 75? I have had other Bio Wheel Filters (5 Gal) and found they worked fine. I do like the Bio Wheels better than other Bio System Filters, but am wondering whether the 75 was actually tested, or assembled with the correct parts.

Rated 2 out of 5 by from Constant cleaning I bought a Penguin 150 due Marineland's great reputation.Unfortunately I am CONSTANTLY cleaning/replacing filters because they get dirty rather quickly (about 1 filter every 2 days). So dirty that the bio wheel stops spinning, and the water exits out the overflow into my tank. Funny thing is the instructions say to replace the filter every 2-4 weeks. It would be nice if the filters lasted that long. Another issue I have is my small fish are getting stuck on the intake of my pump. It would have been a great idea if Marineland made the intake bigger (like for the Penguin 350). Just a thought.

What are the difference in the penguin and emperor power filters

Asked by: Simba
The Penguin is slightly smaller, slightly less flow rate at 350 gph, whereas the Emperor has 400 gph. The Penguin relies on the water flow through the filter to hit the bio wheels and turn them, so a dirty system will affect this drastically. The Emperor has spray bars that continuously spray water on the bio wheels, constantly turning them. It also has media containers for extra media, unlike the Penguin. It also has a flow manifold housing vs the impeller housing of the Penguin. BREX

I have an Emperor 400 and there is no longer water coming out the little holes for the bio-wheels to rotate. I have disassembled and clean everything and still no water from either bar. I have removed the bars and ran to see if water comes out and nothing

Asked by: TabFish
If the spray bars are not working, you are missing the flow manifold cover or it is not staying connected or is damaged. It can be found at the bottom of the flow manifold and snaps over the impeller. BREX

 I have a bio wheel 200. The wheel is terribly noisy due to high speed from being new. I have gently twisted the wheel to improve but did not help much. I have a second smaller filter can I turn off the bio wheel at night and run the quiet one? 

Asked by: Mason305
Just take the bio wheel out and let it float in the tank for a day or two. Also, make sure the bearings are inserted properly. You can also "grease" them with a thin smear of silicone lubricant. Do not turn the filter off at night, no. BREX

Asked by: sean24
Okay, make sure the water level is all the way to the top of the tank. Fill the filter with water as well. Pull out the intake tube, impeller housing and impeller. Inspect the impeller for damage, build up, gunk, etc. (you didn't state whether it is new or older). If it appears dirty, clean it and clean out the entire filter box. If it is new, and impeller is okay, put everything back together again and re-install the filter. If you cannot get it up and running, call 1-800-322-1266. BREX

I bought a tank and it came with the penguin 200 filter. I don’t know how long the previous owner had it but it seems to not keep the water clean. Would you suggest buying a new one? 

Asked by: Newbie14
No, not if it is running. It may need to be cleaned well if it has a lot of buildup, but it is fine if it is running. New tanks take a while to establish (approximately 6 months), and cloudy water is normal initially. It typically clears up after the first few weeks, but it totally depends on how fast you add fish, how much you feed, and how often you vacuum and perform partial water changes. A clean tank is not completely due to the capability of the filter, the filter simply reduces maintenance for you. Depending on the size of the tank, you should vacuum and change 30% of the water at least twice a month, more often if the tank is heavily stocked or has big fish. If the tank was just set up, you may have a bacterial bloom or an ammonia spike and should add Aquarium Bacteria to the tank. Call 1-800-322-1266 for more help. BREX

I bought and installed the penguin power filter 4 days ago. It's made an on and off again horrible grinding sound. Please help.

Asked by: Adrienne
Do you have sand in the aquarium? If so, this is the issue. Whenever using sand with any HOB filter, you need to place filter floss in the strainer or slide a foam accessory over it to prevent the sand from getting in and destroying the impeller. If you do not have sand in the tank, remove the intake tube, impeller housing, and impeller. Check for any grit from the gravel or carbon dust in the motor or on the impeller. Also, check and make sure the impeller is not damaged, warped, or inserted too far up into the intake tube. Call for more help if necessary - 1-800-322-1266. BREX

The power filter does not generate bubbles, unless the water level in the tank is below the filter's spillway. If so, raise the water level. The only way to adjust the flow is to close the mid-level strainer (gray lever). BREX

Clean out the filter box as well, especially the part the impellers sit in and make your water level in the tank is at the top of the tank. Check the purple bio wheel bearings to make sure they are in properly, clean them, and rub a tiny smear of silicone lubricant on them. If the bio wheels are warped, you may need to replace them. BREX

A friend gave me a Penguin200 w an established Biowheel for a 27 gal tank. It creates huge current, looks like the 200 is made for much larger tanks. Thinking about switching to 150, but can i use 200 biowheel or would i have to start over?

Asked by: Audlindal
The 200 model is for tanks 20-40 gallons in size, so should be fine for your tank unless you have some pretty small, delicate fish. You would need a different bio wheel for the 150 and would not be able to use the one with the 200, unfortunately. BREX

Asked by: FireworksMom
Closing the mid-level strainer off may help some, but ideally, you should place some filter floss inside the strainer. This will slow it down or you can put a second cartridge in the filter which will provide more filtration and slow it down. Another option would be to add some other bio media in the main chamber.

I Have a Penguin 350 That I've Been Using For About a Year. I Took My Aquarium Down as I Was Relocating to a New State. Tonight I Set Everything Back Up & My 350 Will Not Take in Water. I've Tried Everything

Asked by: Hoffa
Sorry to hear that Hoffa! So make sure the tank is filled to the top with water, and the filter box is also filled with water. If they are, then I suspect your impeller has separated. It will do this sometimes when kept dry in storage. To inspect it, hold the top and bottom tips between the thumb and index finger of one hand. Take the other hand and flick the blades. The blades should catch the magnet within half a turn and they should rotate together. If not, it is separated. If you need more help, call 1-800-322-1266. BREX

Is it helpful to any other filtering media in the housing? Ceramic pellets? Whatever?

Asked by: Bill1222
Yes, of course. It is always helpful to have additional media such as ceramic rings, bio beads, filter floss, phosphate pads, etc. BREX

installed my new penguin bio wheel filter, it seems to be working fine with the exception of the actual wheel which is not turning. any suggestions

Asked by: alandjanice
Make sure your water level in the tank is to the top of the tank. Also, check the purple bearings at each end of the bio wheel. Make sure they are properly in place, and clean. You might want to rub a bit of silicone lube on them. If they are missing, call 1-800-322-1266. BREX
