Seiryu Rock M86

Seiryu Rock M are stones weighing 750 grams to 1500 grams. Seiryu Rock, also known as Ohko Stone, can release calcium into the water. This type of stone is widely used in the aquascaping 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 an erratic 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.

Seiryu Rock is available from XL to XS.

XL are stones weighing more than 2.5 kg
Large are stones weighing 1.5 kg to 2.5 kg
Medium are stones weighing 0.75 kg to 1.5 kg
Small are stones weighing 0.5 kg to 0.75 kg

By combining these stones, you create a beautiful natural aquascape.
