Seiryu is the Godfather of all stones. The pinnacle of aquascaping rock. Undoubtedly one of the most popular hardscape materials available. The craggy texture and endless details in these stones allow anyone to easily create a natural looking aquascape.
Seiryu may slightly raise pH and water hardness. Aqua soils can help balance that out.
We recommend 2 pounds of stone for every gallon of water your tank holds. A 5 gallon tank would need 10 pounds, 10 gallon requires 20 pounds etc. Of course this is just a recommendation, the amount of stone needed will depend on your plans. It's always nice to have a bit extra for more layout options too!
How we choose stone
Most stones range from 6 cm - 25cm 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.
For single larger stones please check out our WYSIWYG section.
