Black Star Stone Per Pcs

Black Star Stone is a highly popular, premium choice for aquarium hardscapes. It is a 100% natural, volcanic rock that undergoes a tumbling or smoothing process to remove the typical sharp, jagged edges found on traditional lava rock.

Key Features of Black Star Stone

Livestock Safe: Because the sharp edges are completely smoothed out into a rounded, pebble-like shape, it eliminates the risk of fin tearing. This makes it perfectly safe for fish with long, delicate fins like Betta fish, Fancy Goldfish, and sensitive bottom-dwellers. .
Completely Inert: It is a neutral substrate material that does not alter water parameters. It will not leak calcium carbonate or affect your tank's pH, GH, or KH, making it ideal for freshwater planted tanks and delicate shrimp environments.
Biological Filtration: Despite being smooth on the outside, it retains the highly porous interior structure of volcanic lava rock. These micro-holes provide a massive surface area for beneficial nitrifying bacteria to colonize, acting as a natural extension of your filtration system.
Plant-Friendly Texture: Its remaining surface texture provides an excellent anchoring point for epiphytic plants such as Anubias, Bucephalandra, and aquatic mosses.
Striking Aesthetics: Under water, its dark charcoal and deep grey tones intensify, often revealing subtle white speckling or highlights that contrast beautifully against bright green live plants.
