Ceramic Rings


Replace your media ceramic rings occasionally.  Your best bet to keep the beneficial bacteria in your nano cube aquarium or tank is to alternate weeks and replace a different week than you replace other items like carbon and sponges or bio balls.

If you replace all of your media at once, you will lose too much good bacteria!


Ceramic Rings for the JBJ Nano Cube are ideal for fostering beneficial bacteria.  Your fish will appreciate this.
