Finally, a Worry-Free Algaecide that Works Instantly on Even your Toughest Algae. Unlike other aquatic algaecides on the market today, GreenClean works on contact to control algae (especially String Algae) in water gardens, ormanental ponds, fountains and other water features. It is activated by water and safe for all animals once it is in liquid form. Avoid keeping granuales where birds and small animals can ingest them.

GreenClean does not harm fish and aquatic life and starts working instantly. GreenClean immediately begins fighting algae blooms, releasing vital oxygen into the water as it biodegrades. SAFE for Koi and other pond fish and Aquatic Plants. It is recommended that you rinse it off the plant leaves to avoid burning. EPA approved.
