Natural Pond Cleaner for Large Ponds, 10 lb Biological Maintenance Supernatural PondMagic delivers broad-spectrum biological maintenance to large ornamental ponds, addressing organic debris, bottom sludge, excess nutrients, and filter performance in a single treatment. The 10 lb pail provides enough product for a full season of biweekly treatment for ponds up to 10,000 gal (38,000 L), or season-long weekly treatment for systems in the 5,000 gal (19,000 L) range. Large-System Biological Balance Large koi ponds and heavily stocked systems generate organic load that smaller-format treatment products cannot keep pace with. The 10 lb pail ensures adequate product volume to treat consistently at the doses needed to make a difference in larger systems. Irregular or under-dosed treatment is less effective than consistent, properly measured applications. Coverage Ponds up to 10,000 gal (38,000 L) Format Dry granular Weight 10 lb (4.5 kg) Safe For Koi, goldfish, aquatic plants, wildlife Season Spring through fall when water is above 10°C (50°F) How to Use Dissolve in a bucket of pond water before distributing throughout the pond. Apply every one to two weeks from spring through fall, scaling dose to pond volume. Increase to weekly during summer peak when fish feeding rates and organic load are at their highest. Combine with aeration for maximum biological activity. Store sealed in a cool, dry location. Ideal for large koi ponds, water gardens, and ornamental features from 5,000 to 10,000 gal (19,000 to 38,000 L) requiring consistent biological water quality management.
