When organic sludge builds up in the aquarium gravel bed, it smothers the natural aquarium cycle, creating an unhealthy environment for fish.
Weekly addition of API STRESS ZYME ensures a healthy dose of beneficial bacteria to break down organic matter. This all-natural formula contains a unique blend of 5 beneficial bacterial strains selected to reduce sludge build-up in an aquarium, and boosts the biological filter to keep the aquarium healthy and balanced. STRESS ZYME may be used in both fresh and saltwater aquariums.
