The famous Seiryu Stone is blueish grey in color with sharp jagged edges. Most of them consist of deep cuts and crevices within the stone itself. Seiryu Stones frequently have calcite veins within their layers, creating a great contrast from its brilliant blueish grey hue to its stripes of white veins. Seiryu stones will definitely raise your pH and gH depending on how many pounds per gallon you have added into your tank. They are completely shrimp safe for Red Cherry Shrimp, Ghost/Glass Shrimp, and Amano Shimp. Please note that this is a natural material and it comes in different textures and characteristics, some have more crevices, and some have less crevices.
The SR Aquaristik Seiryu Stone Aquascape Kit contains a minimum of three hand selected, precleaned, heat treated and wrapped stones, ideal for creating the ultimate Aquascape. Each kit contains a minimum of 12 pounds/ 6kg of beautiful Seiryu Stone.
