Ultum Nature Systems Controsoil Freshwater Aquarium Substrate Normal Black 10 Liter Volcanic Ash Formula

Ultum Nature Systems Controsoil is a premium freshwater aquarium substrate engineered to create a thriving environment for planted tanks, tropical fish, and freshwater dwarf shrimp. Crafted from high-quality natural soil and volcanic ash originating from Mount Aso in Japan, this andisole-based substrate features an optimal normal granule size of approximately 5 millimeters. The unique composition provides a porous texture and rich internal structure that serves as an ideal rooting medium for aquatic plants while offering superior surface area for beneficial bacteria colonization. Designed with a low ammonia release formula, it significantly minimizes the risk of unwanted algae blooms during the initial setup phase. Furthermore, it naturally buffers and softens aquarium water, stabilizing pH levels around 6.8 to suit sensitive livestock. By actively absorbing impurities from the water column, this substrate helps maintain crystal-clear water quality, ensuring a balanced, healthy ecosystem for your aquatic pets and live vegetation.
