Rated 5 out of 5 by from Great filters, healthy fish! I love this filter line! When this first came out many years ago, I remember setting one up in the fish store I worked at, and the bio-wheel was a new concept. It looked funny at first, but my skepticism quickly changed when I saw the results of this filter! Healthy fish, clear, clean water and simple maintenance. I have gone on to use the filters for most of my basic fish tank set ups. A little perplexed on all the negative reviews, but you will not be disappointed in this filter. You never replace the bio-wheel, and only clean/replace the cartridge as the bio-load (number/types of fish) dictates. You can buy something else, but in the end, once you try one of these, you will probably not buy other hang-on-back type filters.For the uber fish nerd, the bio-wheel grows both aerobic and anaerobic bacteria, giving you a more balanced spectrum of bacteria to clean the water and keep your fish happy.

Rated 5 out of 5 by from Only the best I have used a number of HOB filters over the years and Marineland only puts out quality products. The Penguin filter will be the last filter you buy.

Rated 1 out of 5 by from Worst filter I've ever owned! These filters are garbage! I've had a couple filter for months. They constantly makes a grinding noise since I've had it. I've even taking it apart and put it back together multiple times to try and fix it. I've read this is very common in these filters. Stay away and go with an aquaclear .

Rated 5 out of 5 by from Great Quiet filter I bought a 10 gallon Marineland with a Penguin 75 filter about six months ago. It was to replace a smaller tank. I love the easy set up and the waterfall filter. It has been working out great.

What size filter cartridge is supposed to fit in the additional media slot for the penguin 200? It seems the rite size C cartridge is slightly too big for that slot.

Asked by: Aquamanshane
You can use the Rite Size C, or buy a media container and customize it to suit the tank's needs. The C cartridge fits it, but sometimes may have extra floss on the sides you need to trim off. BREX

Hello I have the emperor 400. I don’t know if it did it before since I just added my fish from my old tank until today but the rear lid keeps popping up and when you lift it up the filters float up. Is there something I might be missing to stop this?

Asked by: Ericw6311
Well, that's odd, indeed. We have never had anyone report that issue, that I am aware of. Make sure the cartridges are in the slot in back, and the blue is facing the front of the tank. You can place the media containers in front of the cartridges, filled with carbon or bio beads, etc. If you happen to have an air stone near the filter, shut it off for a while, and see if the cartridges still pop up.

While medicating a tank with chemicals that harm neither plants nor snails, do I remove the bio wheel, or just the carbon?

Asked by: ArmyWife
Thank you for contacting us, ArmyWife, and for your and your husband's service to this country! You would only need to take out the carbon, not the bio wheel. BREX

Hi... I have a penguin with the two bio wheels. I cleaned out and emptied the tank to sell.. but after a few months decided to keep the tank. Should I buy new biowheels or am I ok to continue with the ones I have even though they have been dry for a bit?

Asked by: Brittneyadams
You can definitely use the old ones as long as they are not damaged or warped. They will build a bio load again after a few week, as if they were brand new. BREX

I just picked up a Marineland Bio-Wheel Penguin Power Filter, Size 200 and I was wondering if there was a way to adjust the water flow? I want to slow the flow down

Asked by: Steve519
You can close off the mid-level strainer, and this will effect the flow somewhat, but not a lot. BREX

My Bio-Wheel is not turning and I followed every step and instructions you mentioned.

Asked by: ABUELA
Then at that point, you call in to talk to a technician to make sure you've done everything possible and done it correctly. If so, you may have warranty if you have your receipt as these filters have a 3 year warranty. BREX

a put athank you new bio-wheel 200 in and the motor is noisy. ill it quiet?

Asked by: jay s
Hello, jay s! We're sorry to hear the motor is noisy. That indicates an issue with the impeller. We suggest turning the filter off, removing the intake tube then cleaning the impeller and impeller well. For troubleshooting help please call Marineland at 1-800-322-1266.
