ANS Dragon Rocks 20kg Box for Larger Aquascapes

This 20kg box of Dragon Rocks, sold across S, M, L and XL grades, is aimed at hobbyists building bigger layouts who want a consistent supply of the same craggy, earthy stone in one go. Dragon stone (Ohko) is an inert, clay-based rock that will not shift your water hardness, which suits our naturally soft local tap water and keeps it usable for shrimp, planted, and community tanks alike. The pitted, holey texture creates instant hiding spots and a rugged, natural backbone for a scape.

Buying a mixed-grade box lets you place large anchor stones for the main structure and scatter smaller offcuts to carry the visual line down to the substrate, the trick that makes a hardscape look like one connected formation rather than separate rocks. Rinse and scrub off loose clay dust before placing, as the soft surface sheds fines that cloud the water early on. For HDB floor-loading, remember stone is heavy, so plan rock volume against a sturdy stand.
