Natural stoneSlide-proof, acid & alkali proofSound absorbing and insulationFeatures of Volcanic Stone:-Natural stone, sound absorbing and insulation-Heat absorbing and preservation-Water absorbing and slide-proof-Acid & alkali proof-Not radiation-Not permeation-Not poisonous and not odor-Green and environmental-protection products with high quality-Improve water quality-Perfect for providing the ideal living environment for your aquarium because it has beneficial denitrifying bacteria.-Ideal for Aquascaping especially for bucephalandraBENEFIT OF USING LAVA ROCK1.Stable water qualityThere are two parts here: PH stability, which can adjust the water that is too acidic or too alkaline to be close to neutral automatically. The content of minerals is stable. Volcanic rock has the dual characteristics of releasing mineral elements and absorbing impurities in the water. When it is too little or too much, its release and adsorption will occur.2.Cultivation of nitrifying bacteriaThe high surface area produced by the porosity of volcanic rocks is a good hotbed for cultivating nitrifying bacteria in water, and the positive charge on its surface is conducive to the fixed growth of microorganisms. It has strong hydrophilicity and can reduce the NO2 and NH4 that are caused by various reasons in the water, which are very toxic to vertebrates. Conversion into NO3 with relatively low toxicity can greatly improve water quality火山石简介：火山石是一种功能性的环保材料。它是一种珍贵的多孔石头，由火山喷发过程中的火山玻璃，矿物质和气泡形成。它包含钠，镁，铝，硅，钙，钛，锰，铁，镍，钴，钼和其他数十种矿物质和微量元素。它没有辐射。它具有远红外电磁波。天然石材防滑，耐酸碱吸音和隔音火山石的特点：-天然石材，吸音和隔音-吸热和保存-吸水和防滑-耐酸碱-不辐射-不渗透-无毒无味-高质量的绿色环保产品-超细高品质的产品-习惯于室内装饰，室外装饰及铺装公共广场-改善水质-完美的为您的水族馆提供理想的生活环境，因为它具有有益的反硝化细菌。-特别适合bucephalandra的Aquascaping的理想选择
