Lava Rock Black per kg

Black Lava Rock is formed from cooled volcanic lava and is prized in aquascaping for its dramatic dark color, lightweight nature, and extraordinary porosity. Its vast surface area makes it an excellent biological filtration medium when used in sumps or filters, in addition to its decorative uses. Mosses, Java Fern, and Anubias attach readily to its textured surface. It is essentially inert and has minimal impact on water chemistry, making it suitable for most freshwater setups.
