The filters work as expected.

Run it under water or let it soak for 5 minutes before putting it in your tank

Easy to use..for my 55 gallon fisj aquarium.

Nice product, delivered fast.

These are my favorite filters. They are less expensive on Amazon than at the pet store.

They do a good job of keeping the water clean and puts the right bacteria in the tank.

Had to change filter bag within a week. Other brand I could change once a month.
