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.

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!

Bad shipping

I loved the filters, but when they came, the big box they were in had a tear in it, and all the little boxes of filters inside were smashed in one way or another. Loose carbon filter medium was inside the big box, and when I got the little boxes out, I had black all over my hands. Not a pleasant experience, but....I guess it's a matter of "do you want them or not."

great price

The same six filters would cost me $30 at my local big box pet store. Same filters, barely more than a quarter of the price. Chewy wins again!

never again

should be two stage white and blue media but the blue media is so thin like something sprayed on you can still see the white media white underneath the blue very thin layer. I think they are bootleg copy cat filters

A good filter

Ive used Marineland for quiet some time now and I always go back to them! The water doesn't fog up and it doesn't smell one can last up for a month or even more. plus chewy always has the best price so I always order from them and ive never had an issue.
