Seiryu Rock M98

Seiryu Rock M are stones weighing 750 grams to 1500 grams. Seiryu Rock, also known as Ohko Stone, can release lime 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 jagged 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 osmosis water.

Seiryu Rock is available from XL to XS.

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

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