ANS Manten Rocks 20kg for Iwagumi and Nature Scapes

Manten stone is a favourite for stone-led layouts, with a muted grey tone and subtle veining that reads calm rather than busy. This 20kg lot of mixed sizes gives you a working set: one or two larger main stones plus supporting and accent pieces, which is exactly what an iwagumi or nature-style composition needs. Buying by the bulk lot also means you can select cohesive pieces with matching grain rather than hoping a small pack works together.

Rinse each rock well before use to clear quarry dust that would cloud fresh water. With 20kg in play, mind the load: spread the weight, dry-stack and photograph your layout before flooding, and make sure your stand and floor are happy under it, a fair point in HDB and condo tanks. Manten is generally inert and shrimp-safe, so it sits comfortably in soft, slightly acidic SG water without swinging your parameters.
