Marineland Rite-Size Cartridge Refills (6-Pack)

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.

Works well

Works as intended

need to keep the water clean

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 product for a great value. Easy to use.

Great product for a reasonable amount of money!

I bought these for my Marineland 5 gallon portrait aquarium
