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. 1 No Rinsing Required Inhibits cloudy water by actively absorbing impurities 2 Low Ammonia Release Promotes and accelerates beneficial bacteria growth 3 pH & kH buffering Buffers water to slightly acidic pH and lowers total water hardness for better aquatic plant nutrient consumption environment 4 Optimal For Fish And Shrimp Suitable for all fresh water inhabitants such as tropical fish and shrimp that prefer slightly acidic aquarium water 5 Designed For Planted Aquariums Granule composition and sizes provide optimal oxygen exchange and rich nutrients for aquatic plants AVAILABLE GRANULE SIZES AND COLORS EXTRA FINE Great for top-offs and nano tanks FINE Ideal for shorter root aquatic plants such as foreground plants NORMAL The standard for larger scale aquariums and aquatic plants with thicker roots BLACK BROWN APPLICATION GUIDE Volume Tank Size Recommendation 1 Liter 2 Gallon TankUltum Nature Systems 20C Cube Tank 3 Liter 9 Gallon TankUltum Nature Systems 45U Standard Tank 10 Liter 20 Gallon TankUltum Nature Systems 60U Standard Tank
