ANS Guryi Rocks (5-40cm) Sold Per Kg for SG Tanks

Buying Guryi rock by the kilogram is how we help hobbyists hand-pick exactly the pieces a layout needs, from a 5cm accent stone up to a 40cm centrepiece. This per-kg option suits anyone refining an existing scape or working to a precise vision, and the sizing chart on this page is a genuinely useful starting point for estimating how much rock a 2ft, 3ft or larger tank will swallow once you account for mixing wood into the design.

One practical note for Singapore keepers: as the description states, this stone buffers pH and KH upward. Our local tap water is already soft and slightly acidic, so a heavy rockscape will nudge parameters harder, which is great for African cichlids or livebearers but worth watching if you keep soft-water shrimp or blackwater species. Test before and after scaping so you know where your tank settles in our warm 27-29C conditions.
