Seiryu Stones appear with a more bluish hue when submerged underwater. We recommend to give the stones a rinse under warm water and a light scrub to get rid of any debris it may have. The stones naturally will increase water hardness and pH for most aquariums, but water changes help make the water chemistry less notable.
