The Activ Betta Aquarium Sand is a great way to create an artificial ocean environment in your home. The sand is made of natural quartz that has been processed with a special formula to make it easy to clean and smell neutral. The sand is also low in silica and phosphate, so it won’t affect the pH level of your water. The Activ Betta Aquarium Sand is available in a black gravel form that is perfect for creating an ocean feel in your home.
