Blue Mountain Seiryu Stone - ALA per pound

Blue Seiryu Stone is a darker, bluish-grey variation of Seiryu stone. It has a darker tone and also contains bits of white veins that really make this aquarium stone really pop in a planted tank when used with colorful aquarium plants.

Seiryu may slightly raise pH and water hardness. Using aquarium soil can help to balance this out to optimal levels for your aquarium livestock.
