WIO - Darwin Black Lava Stone

Darwin Black Lava Boxes 

Darwin Black Lava is a jet-black volcanic stone defined by deep crevices, rich rugged texture, and naturally high porosity. Its dark coloration creates bold, dramatic contrast against plants and wood, making it an exceptional choice for aquariums, terrariums, and nature-style layouts. Underwater, its porous structure enhances depth and provides ideal surfaces for mosses and epiphytic plants.

Available Sizes:
Mega Box – 26 lb (12 kg) – Ideal for 2'–4' (60–120 cm) aquariums
Nano Bags – 3.3 lb (1.5 kg) – Smaller pieces for nano tanks
Available per pound as well
