Marineland Rite-Size Cartridge Refills (6-Pack)

Works, fast delivery.

Good value for money. These filter cartridges serve their purpose.

Perfect product

The carbon pellets barely fills half of the filter on the backside. My tank is pretty clean and I still need to clean or replace the filter every two weeks.

Great value thanks

good deal!

i like the ease of using these filter cartartages. thank you joan neighbors.

PERFECT FOR OUR SMALL TANK!

They arrived with charcoal in the bottom of the bag! The filters were stained black and There was hardly any charcoal at all in the actual filters! Worst filters I have ever purchased on Amazon! Having to go out of my way to ship them back is such a hassle. Will never purchase this brand again!

The filters are exactly what I was hoping for.
