Pond Water Conditioner, 1 Gallon for Large Ponds Supernatural PondPrep neutralizes chlorine and chloramines in tap water on contact, protecting fish and biological filter bacteria from chemical damage. The 1 gallon size covers large ponds up to 4,000 gal (15,000 L) per treatment and provides a season-long supply for ponds requiring regular top-offs and partial water changes. Cost per dose is significantly lower at gallon volume than smaller sizes. Bulk Conditioning for Large or Active Systems Large koi ponds lose water to evaporation at a meaningful rate in Canadian summers and require regular partial water changes to manage nitrate levels. For a 3,000 gal (11,000 L) pond doing monthly 20% water changes, a gallon of PondPrep provides enough product for multiple months of treatment. Having it on hand means you are never in a position of adding untreated tap water because you ran out of conditioner. Coverage Up to 4,000 gal (15,000 L) per treatment Format Liquid concentrate Volume 1 gal (3.78 L) Neutralizes Chlorine, chloramines Safe For Koi, goldfish, aquatic plants, wildlife How to Use Dose based on the volume of tap water being added, not the full pond size. Apply at the point of water entry, through the hose stream or directly to the pond surface. For large water changes, add PondPrep first, then begin filling. Store with lid sealed in a cool location between uses. Safe for immediate fish exposure after application. Ideal for large koi ponds, heavily stocked ornamental features, and pond professionals conducting regular water changes on systems from 2,000 to 4,000 gal (7,600 to 15,000 L).
