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

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.

Yes they did

the package sounded like sand or charcoal(yes) loose in the packaging! And there was charcoal from the filters but hopefully the filters still work!

I like my filter that why I buy it its cheaper then store

Works well

Filters don’t last more that a few weeks but filters very easy to change out and fairly inexpensive.

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

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.

could not use wrong size to small

Exactly as described. Works great for my 10 gallon tank, if I had a larger tank I would recommend investing in a slightly stronger irrigation system for optimal waste removal.
