UNS Controsand 3L - Kona - Gravel

Ultum Nature Systems Controsand is a natural substrate for the planted aquarium. It will not alter water parameters and can be used in various applications. Rinsing is recommended before use to remove finer grains.

Kona Controsand is a rounded pebble gravel designed for freshwater aquarium use. Kona’s deeper tones can be used as a supporting feature or to create excellent contrast. Like other Controsands, Kona can be used alone or mixed with other substrates for a custom look in planted tanks, terrariums, paludariums and more.
