Marineland Rite-Size Cartridge Refills (6-Pack)

Love them

Filtration

Aquarium

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 .

Works as intended

they work well and my fish are thriving, thank you very much!!

Excellent
