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. 

Vesuvius Controsand is a chunky gravel made from Black Lava Rock. Its porous surface supports a healthy ecosystem while its inert composition is ideal for freshwater aquariums. The substrate is versatile and can be used as a standalone choice or in combination with your favorite cosmetic sand. Vesuvius Controsand would work particularly well in shrimp tanks!

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.

Key Features & Benefits

  • Inert Foundation: All varieties of Controsand are biologically inactive and intended for cosmetic usage. It will not alter water conditions, 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. Black Lava is naturally porous and will provide the perfect surface for supporting plant growth, if desired. 
  • Compatible with Bottom-dwellers: Perfect for shrimp or other bottom-dwelling species that sift through sand.
