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.

Some bubble wrap or any foam would go a long way. Big box heavy items banged all around in Shipping with light items with charcoal. Opened box and everything was black from charcoal fish filters. Some simple damage prevention in shipping would’ve prevented all this. First and last purchase from chewy

It’s a filter. Have ordered them a bunch of times and this time out of the three boxes I ordered two of them were crushed. Filters seem to be ok but random guy showing up in my driveway to deliver package is a bit unsettling.

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.
