This item qualifies for free shipping!

Ultum Nature Systems Controsand is a line of decorative sand substrates designed for use in planted aquariums and aquascaping. 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.
