CaribSea Super Natural Aquascapes Peace River Sand

CaribSea Peace River is a smooth-grained substrate in the Super Natural Aquascapes range. Its typical 1–2mm grains suit a fine riverbed-style layout, and CaribSea specifically identifies Peace River as an option for bottom-dwelling fish such as corydoras.

Rinse before adding it to the aquarium, following the manufacturer's instructions. Leave the substrate accessible around plants and decor for maintenance. If replacing an established bed, work in stages and monitor water quality: removing substrate also removes part of the aquarium's existing biological filtration.
