How much Crystal Plex should I use?

Properly measure your pond to find the square acreage and average depth. One gallon of Crystal Plex, liquid copper sulfate solution will treat a surface acre 1 to 2 feet deep. Example: 1/2 acre pond 4 feet average depth, mix 1 gallon with 8 to 10 gallons of water. (Water is to help spread the product, not to dilute.) See labeled instructions for all application rates.
