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.

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.

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.

Wrong measurements on site

The site states this product is 6.5x4.5x6.75. It's really 6.5x5.5x6. Needless to say, it doesn't fit. Also when I open the box there was more loose carbon that fell into my floor than in the actual cartridge.

Fits Marineland Power Filter

These are the only filter cartridges on the market that fit the Marineland filter I have on my tank. They work great and are easy to change out. Would be nice to see a little competition from another brand, but at least these aren't too pricey.

Product is great, but customer service is even better!!!

I’ve been using this product for quite some time for one of my clients freshwater tanks for a long while now, the quality is always good, but the customer service is ALWAYS nothing but A+++ The ones I’ve ever dealt with have always been customer oriented and are the platinum standard for customer service in my opinion!
