Do you put the filter in the Bio-Wheel with the blue facing towards the tank?

Answer by Chewy • Dec 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 Chewy • Aug 20, 2019
Replacement Bio-Wheel bearings are available on the Marineland website.

If you have an angelfish, you know that a good filter is important. I can typically rinse these filters once or twice before replacing with a new filter. I'd say a filter lasts about a month. Your experience might be different depending on how many fish you have and how big they are.

Having the cartridge filter letter stand out, so you can easily find the product

This is a re-order and we have been using this product for a few years for the fish and we are quite satisfied
