Marineland Rite-Size Cartridge Refills (6-Pack)

I monitor my water level Constantly always use this product because it works the way it’s intended

Great value thanks

My aquarium.

Great product for a reasonable amount of money!

Been using these for about a month. Very happy with the water quality in my Marinland Portrait 5 gal. Easy to change the filter. Shipment arrived on time - very good packaging.

Great to have these on hand

These work great in our two beta tanks. They really do make a world of difference in the amount of time the tanks stay clean!

Perfect

BEEN USING YOUR FILTER AND IT KEEPS THE UNIT CRYSTAL CLEAR,,,

The filter did not have very much carbon in it compared to the one that came with the tank.
