UNS Strata Seiryu Hardscape
One-piece Iwagumi rock formations cast in lightweight aquarium-safe resin to look like Seiryu stone. Type 1 is taller and more dramatic, Type 2 is lower and more open to leave room for a carpet.
Updated
Best for
First Iwagumi builds in 20-40 litre tanks, and soft-water shrimp keepers who love the Seiryu look but not its effect on KH.
Worth knowing
It is resin, not real stone, and up close it will not have the variation of natural rock.
What stands out
- Two designs, both about 1.1-1.3 kg
- Seiryu look without the hardness increase
- Sized for UNS 5N and 45U tanks; both together suit a 60U
- Safe for fish, shrimp and plants
