CaribSea Eco-Complete Planted Aquarium Substrate (20 lbs)

CaribSea Eco-Complete is a complete planted aquarium substrate packed with live beneficial bacteria and rich in minerals from basaltic volcanic soil. Unlike inert gravel or sand, Eco-Complete contains over 25 minerals that plants use for healthy root growth — no laterite, soil additives, or separate root tabs needed right out of the bag. The heterotrophic bacteria in every bag jump-start the nitrogen cycle so new tanks establish faster.
