Seiryu Rock M are stones weighing 1kg to 1.5kg. Seiryu Rock, or Ohko Stone, can release calcium into the water. This type of rock is widely used in the aquascape world and is rightly one of the favorite stones due to its rugged structure and beautiful relief.

Seiryu stones are dark in color and have a rugged appearance. It is the ideal stone for 'mountain scapes'. Due to its dark appearance, this type of stone perfectly matches fresh green aquarium plants.

This stone is calcareous and will increase the hardness of the water. For shrimp scapes, it is important to lower the pH with a pH-lowering substrate or by mixing with RO water.
