Soil derived from black humate. Ideal substrate for planted aquariums and shrimp nano aquariums. Lowers pH and softens water. aquasolum is a light, porous humate substrate. Humate contains most of the trace elements necessary for the development of plant life. Organic humate enhances root development and promotes chelation, a process by which insoluble materials are gradually transformed for use by plants. As a result, humate contains valuable plant nutrients not found in chemical fertilizers. In addition, its tendency to lower pH and soften water makes it ideal for keeping freshwater shrimp.
