Description
Volcanic natural substrate for aquascaping.
Key Features: • Volcanic rock substrate as stable foundation for rock and root wood constructions: dedicated substrate for aquascaping aquariums. • Basis substrate for natural aquariums: porous volcanic rock ensures water circulation at the bottom. Supplies plant roots with organic plant nutrients. • Vigorous plant growth: ideal oxygen supply and circulation through open-pored structure. Long-term supply with nutrients and minerals. • Safe foundation, no slipping: volcanic rock becomes firmly interlocked. Ideally suited for a firm foundation.
