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

I had another pump that didn’t work as well as I needed it to. I purchased the Marineland pump and these are the perfect replacement filters. The original brand and a better price than the pet stores. Thanks Amazon for a great deal. I will purchase again.

Quick transaction and perfect for what I needed ! Thanks

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

They work fine! Best to get when on for a good price!

Muy buena calidad y pronta entrega

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.

Perfect fit and great amount so I dont run out.

Works well, good value

Great
