Marineland Rite-Size Cartridge Refills (6-Pack)

need to keep the water clean

I bought these for my Marineland 5 gallon portrait aquarium

These are the correct filters for the Marineland Portrait.

Great value thanks

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

Works well

Works as intended

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 .

Aquarium

Good tank overall, but I can’t rate it more than 1 star because it can trap little creatures. Not sure how, but I’ve had 2 shrimp and a frog end up in the back part of the tank, behind the black panel. When they’re back there, there is no possible way to get them out except by emptying the tank. Wish it wasn’t like this.
