In the West it also goes by the names Dragon Stone, Yin Stone, and Blue Dragon Stone. \u003c\/span\u003eSeiryu Stone has a striking bluish grey character that’s hard to find in rocks. Grey and whiite veins of calcite add focal points in an aquascape as does the jagged grain that invokes rocky outcroppings and mountain cliffs.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWhen used in aquarium aquascaping Seiryu provides a dramatic contrast to the vivid greens of live plants and punchy colors of fish that’s hard to match, especially under high powered plant grow lights.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThis stone will affect the water chemistry of your aquariums. The grey and white veins are made up of calcium carbonate, which will leech into the water column. This is perfectly fine as long as weekly water changes are done to maintain the GH and KH of the tank. I do not recommend using Seiryu with any caridina species of freshwater shrimp, they do well with stable TDS and soft water. Since the stone will constantly be leeching calcium, this will not be easy to achieve. \u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan\u003eBlack Seiryu is the same stone as the regular Seiryu. It has just been refinished with muriatic acid to bring out the nice dark colors. This process is completely safe for any living organisms.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eSold by the pound or set.\u003c\/p\u003e\n\u003cp\u003ePlease let us know how many pieces you would like if you have chosen a higher weight of stone.
