Turn your fishy friends’ home into a verdant jungle river with Carib Sea Super Naturals Jungle River Aquarium Gravel. Made in the USA, this beautiful, uncoated river substrate is naturally infused with water-purifying bacteria that clarifies and conditions your setup’s water. It is inert, meaning it won’t impact the water’s pH levels and will allow the bacteria to proliferate.
