The Pond Guy Oxy-Lift Defense Powder Scum & Stain Treatment for Waterfalls, Rocks & Fountains, 2 Pound 

Over time, rocks, streams, and waterfalls can become covered with algae stains and other buildup. Use The Pond Guy Oxy-Lift Defense, a powerful pond cleaner, to "lift" debris from your waterfall spillway, stream, stone, birdbath, concrete, pond liner, or anywhere stains occur. This effective rock cleaner reduces pond maintenance time and can eliminate the need for yearly pond shutdowns and clean-outs. Oxy-Lift Defense reduces scrubbing time by quickly lifting debris off pond liners, rock shelves, gravel, and waterfalls.  Just sprinkle Oxy-Lift Defense directly onto debris-covered areas, and watch it instantly foam and clean the surface. To apply, shut down waterfalls or streams to ensure optimal contact. Apply the powder over the affected areas, avoiding direct contact with plant foliage. Oxy-Lift Defense should not be diluted. Wait 10 to 15 minutes before turning waterfalls or streams back on. The pond may become cloudy after application, but this is temporary and will clear as debris is removed using a pond net, vacuum, or filtration system.  This treatment is a trusted pond cleaner for outdoor ponds, ideal for freshwater ponds, patio fishponds, backyard water gardens, pondless water features, and aquascapes of all sizes. It is safe for animals, including frogs and other wildlife, when used as directed. It is also safe for pond equipment, making it a reliable fountain cleaner. Oxy-Lift Defense will not harm your other pond equipment or accessories.  The Pond Guy products provide superior care for your pond, promoting a cleaner and more balanced ecosystem. The Pond Guy offers many solutions to help resolve your pond problems. Oxy-Lift Defense works well alongside natural treatments like Muck Defense muck reducer, which contains beneficial bacteria that digest organic debris, also known as pond scum or sludge.
