Rated 3 out of 5 by from They work great but... I have two (1) is a 150 and (2nd) is a 350. Impellers in both have gotten loud. My 350 came with a damaged rubber grommet on one end but didn't notice it till a month after i bought it. Now i'm looking for new impellers after only 6 months. Thats proving to be a challenge as well!

Rated 5 out of 5 by from Multifaceted Filtration For Clear, Clean Water. I recently bought the Penquin 150 Bio Wheel Filter. It is a well built system that oxgenates the water thoroughly. There is room for 2 filters and other biomaterials. The rotating wheel for added biofiltration is a nice touch. It is also a fairly quiet unit. The only drawback is the outflow current is pretty strong. My fish can deal with it, but if you have a planted aquarium, you may want to move your plants about 4 inches or more from the outflow, as I did. I also have rocks and plants setup so my fish have a quiet spot to retreat to. The strength of this filter, however, makes for good water circulation.

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 4 out of 5 by from Cleans well I bought this filter about a year and a half ago. I have really liked it until recently. The propeller has gotten really loud. I have tried cleaning it, oiling it, only helps for 10 min. Any suggestions?

I bought this unit from Petco less than a year ago. It was stopping a lot so I thought it was defective petco swappes it out. The new one did the same thing. I emailed you guys and you sent me a new impeller. I installed it and it’s still doing the same. 

Asked by: Anthony M

I'll likely be getting a 55 gallon tank, would you recommend the Penguin 200, 350 or the emperor 400? It seems I can get the emperor 400 for cheap too.

Asked by: WC100
Thanks for asking! The Penguin 200 would be a great option for your tank if it is stocked appropriately. If you are overstocked or have high waste producing fish you may want to use one of the bigger filters. For more personalized advice please call Marineland at 1-800-322-1266. We are happy to help!

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
