Triple Layered Coconut and Bamboo Carbon Aquarium Biomechanical Filter Sponge

Our Castle Dawn Aquatics biomechanical aquarium filter sponge is triple-layered, using coconut and bamboo carbon as the outer layers. Bamboo carbon absorbs harmful chemicals as well as releases essential minerals into the water such as potassium, sodium, calcium, and iron. Coconut carbon is 50% more effective at absorbing organic and inorganic chemicals than any other activated carbon. With the carbon layers, the sponge is extremely effective at removing discolouration from the water caused by algae and tannins, keeping your water crystal clear.
