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

Excelente

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.

Good filters and a good price, works very well in. my fish tank

very good.

Ive used these for years and are a fair value when bought in bulk.

Muy buena calidad y pronta entrega

Work great!

Good seller

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.

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!
