Macadamia nut shells are a natural product which is a great addition to your aquarium. Macadamia nut shells may release tannins and other compounds that can help lower the pH and soften the water, creating conditions similar to those found in natural habitats. Macadamia nut shells also can provide a surface for beneficial bacteria to colonise, the bacteria can help to improve the quality of the aquarium water.

I recommend that you rinse the shells before adding them to your tank
