Ultum Nature Systems Controsand is a line of decorative sand substrates designed for use in planted aquariums and aquascaping. Bora Controsand is a fine natural sand that contains a mixture of lighter, sandy granules. This color palette takes inspiration from natural white sand banks and is a great choice when recreating beach-style aquascapes. Lighter-toned sand also works well as an accent against a darker base substrate. It also compliments vibrantly colored aquatic plants and livestock.
Whether you're setting up your first aquascape, or you've been in the hobby for years, Controsand is easy to use. Just rinse the substrate gently to remove finer grains, then spread it evenly in your aquarium for a naturally earthy tone.
