Rated 5 out of 5 by from Better by design... Bio Wheel technology is a superior form of wet dry biological filtering. IMO... there is simply no better power filter available. The Ribbed Back cartridge design keeps water flowing through the Black Diamond carbon instead of channeling it around or having a tea bag effect. These filters are well thought out and have proven performance. I give it two thumbs up... And my fish give it TWO FINS UP!

Rated 5 out of 5 by from Wow What a Difference I had an aquarium when I was a teenager, and even with several plant-eating fish and a north facing window, algae was always out of control. We bought our first Penguin filter a year ago as part of a kit that was on sale for 50% because of the price and complete kit, and we were happy to find what a difference the biowheel makes in overall aquarium cleanliness. No more out of control algae. There was a little, but nothing a scrubber and a low dose of algaecide didn't take care of. Water clarity is crystal. Our fish look very happy, and so do we.

Rated 5 out of 5 by from Works well, reliable, and customizable. I started being deployed for combat frequently at high tempo, so I gave away my fish and let my parents keep my tank and equipment until I was ready. My old 20H setup sat empty in my Dad's garage (in Iowa) for TEN YEARS. I just got all that stuff back and set it up to see what I need to purchase. I cleaned the Penguin Power Filter housing, held the pump section under running sink water, and nudged the turbine with a chopstick to get it moving again. The pump turned on and everything works like new!RELIABLE... mine was used with heavy load tank for two years, sat in the elements for ten years, and is now being used again. It still functions great after a decade!CUSTOMIZABLE... there is space in between the filter and Biowheel to put other media such as SeaChem Purigen bag or CNZ ceramic rings.WORKS WELL AS A SCIMMER... I use both my Penguin filter system and an AAP Hydro Sponge filter in my tank with excellent results.LOUD (and QUIET)... the "waterfall" is super loud; however, if you get the water outlet at or below water level, it is SUPER QUIET! I added an extension to the outflow "ramp" in order to achieve quietness, (again, easily customizable). If you keep the waterfall the way it is, the Penguin agitates the surface and oxygenates your water very well.COST... replacement parts can be very expensive! If you shop around, you can find filters for a cheap price; but, the biowheel costs almost as much as a new entire unit! I change the filter cartridge monthly, and am going to continue using the original Biowheel.For a Hang-On-Back power filter, I definately recommend the Penguin series! I will purchase again for sure! I love how well it works as a scimmer, and how customizable it is. It is super loud... unless you customize or modify it for your needs (or keep your water level topped off in the tank).

Rated 4 out of 5 by from Works great once you throw out the BIO-Wheel I have a 20 gallon tank that I bought for some gold fish. Its located in my wife's office in our home. She enjoys the soothing sounds it makes and watching the goldfish while she works.I got a BIO-Wheel 150 for the tank when I first set it up and had similar problems as other reviewers about it running. I even purchased another pump and set that up while I figured out what was wrong.What I found was that fibers which slough off from the BIO-Wheel wrap around the shaft of the impeller that pulls water up and thru the filter. Its a tiny shaft and doesn't take many fibers to slow the impeller down or make it stop completely. I've discarded the BIO-Wheel. I do use an air stone and will be adding an under gravel filter next time I tear the tank down for a thorough cleaning.Except for that issue I like the performance of the filter. I change the filter cartridge once a month and change 2/3 to 3/4 of the water once a week. Goldfish are messy fish but also quite hardy so they take it well.Hope that this is useful information to other users of this product.

Rated 1 out of 5 by from NOISE I bought the penguin 350 exactly 1 month ago and while I was sitting down minding my business it started making an INCREDIBLY loud sound. It is coming from where the impeller sits so even though I just cleaned it 3 days ago I cleaned it again and the sound still persists after an hour of me trying to fix it. I went with marineland because I heard the products were better.... I have filters of numerous previous brands on my others tanks that I have never had a single problem with and I have had them for much longer. My other filters are SILENT compared to this one. Not a happy customer. Hoping to get a response so this can be resolved. One month later is not a good time for it to break considering how much they go for.

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.

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

I am considering buying a Marineland penguin 350 C for a live well I am building.  It will require a longer intake tube to work.  Can you tell me the parts I need to do that?  Also, if I extend it twice, will the pump handle it?

Asked by: Mike7631
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.

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

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

1 Fish in my 55 gal tank is sick. Checked water- high nitrite,6.0 acidity. Did 50% water change. (Tap water is 8.0ph , Can t seem to elevate ph above 6.6. Nitrite is at 20ppm. Changed filters out. Added more oxygenation. Should I replace bio wheel?

Asked by: Eqk9
No to replacing the bio wheel. I believe you are referring to nitrate, NO3, not nitrite, NO2. 20 ppm would have killed anything and everything in the tank by now, if it were nitrite. 20 ppm nitrate is okay, no worries. The acidity could be due to your tap water having low alkalinity, so test for this to see if that is the case or not. If the alkalinity of the tap water is low, then your pH can fluctuate a lot. You would want to add some buffers either regularly or naturally, to prevent the acidity from occurring again. Natural slate, tufa or lava work as do aquarium salt (don't use regularly though) or baking soda. If the alkalinity is good, then you need to really think about what is in your tank and driving down the pH. Since nitrates are at 20 ppm presumably, it shouldn't be these. You can add an ion exchange resin to help such as Purigen. BREX

My Emperor 400 filters used to get really dirty, but not anymore. 120 gallon tall tank, running 2 Emperor 400's and a Fluval 405. Same set up was on my last 75 gallon tank and filters needed cleaned every 2 weeks, and changed once a month.

Comparing the two tanks is like comparing apples to oranges. One is obviously a third larger than the other, and therefore, less likely to get dirty. However, how fast tanks or filters become dirty, depends on types and quantities of fish, your frequency of partial water changes, feeding regimen and more. BREX

My filter got really noisy and I had to unplug it.  Can I float the bio wheel in the tank for a day until I get a new filter or will the good bacteria die? I have another filter that’s running still but don’t want to lose this established bio wheel

Does the PF0075B - Penguin 75 - 10 gal/75 GPH have a flow control? I want it for my 10 betta tank but they can't handle the full open flow. I have 2 males and a female in the tank separated by dividers.

Asked by: Dianad
The only flow control is the mid level strainer. My betta can handle 150 gph, so they should be able to handle 75 gph pretty easily unless they are stressed or ill for some reason. BREX

Does the water rotator have to be changed like the filters

Asked by: Cliff Bregstone
If you mean the bio wheel, no. You only change it if it becomes damaged or warped, etc. BREX
