Api Stress Zyme

Help create a naturally balanced aquarium with API Stress Zyme Aquarium Water Conditioner. Waste, sludge and uneaten food can cause toxic junk, like ammonia and nitrite, to form in your tank. But this water conditioner contains over 300 million live bacteria per teaspoonful to help consume sludge and organic debris, working to keep your gravel and glass clean naturally. Use it weekly in fresh and saltwater aquariums to maintain a strong biological filter and a healthy, clean home for your finned friends.
