Blue Mountain Seiryu Stone is a darker, bluish-grey variation of the iconic Seiryu stone. This specific variety features a deep, moody tone accented by striking white veins that provide a visually stunning contrast, especially when paired with vibrant green or red aquatic plants. Its signature craggy texture and intricate details allow any hobbyist to easily create a natural-looking, mountainous hardscape or Iwagumi layout. Blue Mountain Seiryu is also suitable for non-aquarium use and will work beautifully as a sophisticated accent in terrariums, paludariums, or similar planted enclosures. Stones vary in shape, size, and density. Pieces from packages will range from 3-10 inches. Notes: Seiryu may slightly raise pH and water hardness. Controsoil can help balance that out. If you are looking for larger stones, a minimum weight may be required. Larger stones = higher weight. Email our team if you need assistance. We recommend rinsing stones thoroughly before use to remove any natural dust or sediment. Stone coloration darkens when wet.
