6-Pack, Size B, Rite-Size Cartridge Refills

These are all standard products function as expected

Its the wrong size! It says size B but its actually size C. I have a filter that uses size C so its not a big deal but it should be what the product says.

This is the easiest to use, most complete, and easiest to use kit on Earth. It has guided me thru my new Aquarium and I am so satisfied! This fron a 50 year okd aquarium aficionado. Thank you!

It’s a great product, I’ll keep buying for my tank but Last two times I’ve gotten it from Amazon the box comes crushed and one of the filters are broken I would have sent it back I needed to change my water in my tank.

Awesome Find

The box was completely smashed when it arrived. It was sent in a plastic bag instead of a box. Most of filters seemed ok but the little “filter rocks” were everywhere. I’m assuming it will affect the quality somewhat.

The product was exactly was what I wanted but it came crushed and charcoal from the filter media went all over the floor. The packaging was inappropriate for the merchandise.

Use them in my marineland biowheel filter. Cheaper than pet store price.

Great value

Buy these through Amazon because of value. Only issue is when receiving a lot of charcoal dust in package.
