Mini black lava rock is a lightweight, porous volcanic stone used primarily in aquascaping, terrariums, and succulent soil mixes.

Key Features:

• Water Chemistry: Natural lava rock is inert and does not alter water hardness or pH in most setups, making it safe for sensitive fish, shrimp, and aquatic plants.
• Biological Filtration: Its highly porous, rough surface houses beneficial nitrifying bacteria and provides easy anchor points for epiphytes like Anubias, Java fern, and mosses.
• Preparation: Always rinse lava rock thoroughly under running water before adding it to your tank to flush out fine volcanic dust trapped inside the pores.
