can I buy a wheel for the bio penguin 100
Answer by ChewyJun 17, 2021
The Bio-Wheel is replaceable through the manufacturer.

does this filter work well with betta fish? if not what does?
Answer by ChewyNov 09, 2017
This product is a replacement power filter cartridge for the Marineland Bio-Wheel Penguin 170, 200, 330, and 350 filters, not an actual filter.

Do you put the filter in the Bio-Wheel with the blue facing towards the tank?
Answer by ChewyDec 27, 2018
When installing the filter cartridge, rinse filter cartridges thoroughly and install with blue side facing back of filter box. BIO-Wheel should rest securely in BIO-Wheel Bearings.

can I purchase the Bio Wheel Blue bearings that goes on either end of the Bio wheel inserted in the housing. My filters are ok except after time the Bearing wears out.
Answer by ChewyAug 20, 2019
Replacement Bio-Wheel bearings are available on the Marineland website.

Better than originals

I've been using the originals that came with the filter for a while, washing them as needed. Those are too worn out so I ordered this new oem set. Not only is it a crazy good price! But the product seems to be improved over the original design, the blue filter material looks thicker and more durable than the originals did when they were new. I highly recommend if you have one of the penguin models that use these size C cartridges

Good filters.

Spraying out every week really helps and no need for a new filter every water change.

Convenient and Economical

I'm actually using these in a similarly sized, other than recommend, over the side filter brand. I originally purchased them in a thrift store and found the size compatible. I purchased these as a special deal (item qualified for gift card.) The Chewy price makes them a quick, economical cartridge. While the padding and charcoal are thin, they cover a wide area. For a long time I was rinsing out a thick filter pad that I cut to size, along with a charcoal pad cut to size. It's a lot more work and these make filter media changes easy and fast. I change them out about every 7 - 10 days, let them drain and toss; they can collect a good amount of debris. Will keep purchasing.

Poorly packaged

Product is great but when chewy puts it at bottom with heavy items it gets smashed

Best price for OEM product

Chewy has managed to keep the cost of this product close to pre pandemic rates. These are the manufacturer's filters, not some knockoff. They fit perfectly in my QT tank filter.
