Choosing a quality substrate is an essential part of a nature aquarium as it provides vital nutrients for lush plant growth and helps balance water properties by decreasing the hardness/pH to optimal levels for aquatic plants, shrimp, and most tropical fish.
Originating in Japan, Ultum Nature Systems 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. Controsoil provides the perfect level of nutrients without excess. Many have successfully added livestock within the first 24 hours of a newly set up tank with this substrate without worry. We do, however, suggest making sure that ammonia and nitrites are eliminated before adding livestock.
Controsoil is available in various granule sizes and colors to accommodate user preference and aquatic plant choice.
