Marineland Rite-Size Cartridge Refills (6-Pack)

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

These are the correct filters for the Marineland Portrait.

Perfect

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

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.

Works well

need to keep the water clean

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!

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 .

I bought these for my Marineland 5 gallon portrait aquarium
