Key features

• Dramatic hardscapes: deep crevices and fissures for realistic natural landscapes
• Beautiful contrast: blue tones set off lush green plants in planted and freshwater tanks

Water chemistry: contains calcium carbonate, so it can slightly raise water hardness and pH. This suits species such as African cichlids, but monitor water parameters in soft, acidic water setups.
