Pond Water Conditioner for Medium Ponds, 32 oz

Supernatural PondPrep neutralizes chlorine and chloramines in tap water on contact, making it safe for fish and biological filter bacteria. The 32 oz bottle treats ponds up to 1,000 gal (3,800 L) per application, or provides multiple partial water change treatments for smaller systems through the season. Use it for all tap water additions: initial pond fills, routine top-offs, and water changes.

The Right Volume for Regular Maintenance

Ponds in the 500 to 1,000 gal (1,900 to 3,800 L) range typically require seasonal top-offs to compensate for evaporation and regular partial water changes to maintain water quality. The 32 oz bottle provides enough PondPrep to handle multiple partial water changes before running out, making it the practical everyday size for medium pond maintenance.

How to Use

Add PondPrep to the pond before, during, or immediately after introducing tap water. Dose based on the volume of new water being added. For 20% partial water changes on a 1,000 gal pond, dose for 200 gal only, not the full pond volume. Apply to the pond surface or through a hose stream for even mixing. Safe for immediate fish contact after application.

Ideal for ornamental koi ponds and water gardens from 500 to 1,000 gal (1,900 to 3,800 L) requiring regular water conditioning during seasonal maintenance and top-offs.
