Ryuoh or Seiryu stones are especially attractive for an aquascaped layout. With their rugged exterior they can easily be combined to make larger formations. The grey colour of Ryuoh and Seiryu evokes the image of rugged massive rock formations or mountains. And the textured nature of these rocks allow anyone to create a dramatic under water scene. This makes them highly suitable for Iwagumi layouts.
Seiryu stone may raise your Ph and water hardness, but a good planted tank substrate will buffer it back down.
Sold by the pound or as individual larger rocks. All Seiryu stone is priced at $4.25 per pound regardless of size or amount.
When you select 1lb, 3lbs etc. on the drop down menu the picture will change to the approximately what you will receive for the weight selected. Most stones range from 6cm - 20 cm and are chosen randomly for what we think will work well together. But if you would like smaller, bigger, rounder, sharper or different colours, just request when you check out. We'll do our best.
