    Been using these in one Fluval filter for 2 turtles in about 50 gallons of water for the past 2 months and the water is still so very clear and healthy!

    This replaced my cartridge base media from a Betta 5.5 gallon filter. Its easy to clean just dunk it in old tank water and move around.

    I have a Fluval U2 filter for a 10-gallon aquarium in which I keep a Red Ear Slider turtle. I change these out once every 3-4 weeks. It works surprisingly well, Red Ear Slider turtles are dirty. One box of these has enough in it to fill my filter twice.

    We use this in our Fluval U2 Filter for our turtle. In combination with the other filter refills, it keeps the turtle clean nice for an extended period of time.

    It comes already in a mesh bag, so that is nice. I was worried I would have had to go out an buy one, but it comes included. There are nice and porous. Good for my aquarium
