How to use

Rinse the rocks under running water before placing them in aquariums or terrariums to remove surface dust from packaging. Arrange the boulders directly on the substrate or on hard surfaces to build layers, caverns, and visual focal points. For aquatic use, place larger pieces first to establish a stable structure, then add smaller rocks to fill gaps and create natural transitions. For terrariums, position stones to form shelter areas and to stabilize slopes or plantings.

Usage recommendations

Inspect stones for loose particles before installation and avoid using in systems requiring chemically inert substrates without prior testing. When used in planted aquaria, monitor water parameters after introduction and perform routine maintenance to prevent accumulation of detritus around rock formations.
