Marineland Rite-Size Cartridge Refills (6-Pack)

Great to have these on hand

The filters are exactly what I was hoping for.

They have only25- 30 pieces or less of charcoal in it , it does not keep aquarium clean I have 2 tiny fish in my 5 gallon aquarium , I am trying to find something better to help my aquarium but this is the only size that fits mine .

These are the correct filters for the Marineland Portrait.

Great product for a reasonable amount of money!

need to keep the water clean
