Substrate & Rocks

About

Shop aquarium substrate and rocks for freshwater, planted and marine aquariums. Explore active soil, planted-tank substrate, natural and coloured gravel, sand, pebbles, lava rock and synthetic reef-rock shapes for functional and decorative layouts. Choose options from ADA, Aquaforest and other aquarium brands for aquascaping, plant support, biological filtration and habitat design. Check grain size, water-chemistry effects and preparation instructions to ensure the material suits your aquarium.
