Ultum Nature Systems Controsand is a line of decorative sand substrates designed for use in planted aquariums and aquascaping. All varieties of Controsand are inert and designed for cosmetic usage. As such, the sand will not alter water parameters and has no buffering effect on pH levels or water hardness. Controsand also does not slow-release ammonia over time.

Santa Fe Controsand is a larger-sized natural gravel that contains a mixture of light and dark pebbles. This color palette takes inspiration from the sediment found in and around naturally-occurring river banks and is a great choice for biotope aquascaping. The variable cool and warm hues, as well as the differing pebble sizes of Santa Fe lend itself well as a naturalistic decorative element against an even base layer of 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 distribute to specific areas as a natural accent.

Key Features & Benefits

• Natural Gravel Tone: An blend of variable cool and warm hues, as well as its differing pebble sizes give Santa Fe an authentic look perfect for naturalistic or biotope aquascapes. It’s best used as an accent substrate to recreate the look of a naturally-occurring habitat, such as a riverbed or stream.
• Inert Foundation: All varieties of Controsand are biologically inactive and intended for cosmetic usage. It will not alter water chemistry, including pH levels or water hardness. Additionally, Controsand does not gradually release ammonia into the water column.
• Root Development Support: Controsand’s unique granule composition encourages strong root development, ensuring your plants anchor securely into the substrate and absorb nutrients effectively.
• Compatible with Bottom-dwellers: Perfect for shrimp or other bottom-dwelling species that sift through sand.
