Amtra QUARZ NATURAL BLACK ROCK

Classic quartz stone with neutral grey tones, rugged tear-off edges and deeper indentations. Ideal for layouts that want to offer animal inhabitants plenty of retreats: The stones can be piled up sturdily and still form many small caves and crevices. In terms of colour, they harmonise with lush green plants as well as with reddish or purple beauties. As a genuine natural product, each specimen is unique and shows variations in shape, colour, size and weight.

Note: Be sure to rinse carefully BEFORE placing in the tank! The stones do not release any substances and are neutral to water values. They are NOT suitable for stocking marine tanks.
