Controsoil

Originating in Japan, Ultum Nature Systems x Marfied Controsoil consists of high-quality natural soil and volcanic ash. It’s common for competing substrates to cause ammonia levels to spike. While this helps “jump start” a tank and promotes plant growth; it is toxic to livestock and can cause unsightly algae during initial stages of an aquarium set up.
