The Aqua Medic Bali Sand 3–4 mm is a very pure limestone sand, composed of 98% calcium carbonate and minerals similar to zeolite. Its texture and bright white color make it an ideal substrate for saltwater aquariums, providing a natural environment for invertebrates and fish.
Before use, it is recommended to thoroughly rinse the sand with clear water to remove fine dust. Evenly distribute the sand at the bottom of the aquarium to create a suitable substrate layer for your needs.
