UNS Controsand Tahoe Gravel - Ultum Nature Systems

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.

Tahoe is a rounded pebble gravel designed for freshwater aquarium use. Its neutral color palette is versatile and makes it suitable for a range of popular aquascaping styles. Tahoe works well alone or combined with other cosmetic sands to create a custom blend for planted tanks, terrariums, paludariums and more.

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.
