How much 0f the 32 oz PRI-D should be used per 5 gallon jug.
1 Answer
Tom, a 32-ounce bottle treats 512 gallons. On the side of the bottle, it shows measurement lines starting at 4 ounces and going up by 2 ounces. The top fill chamber is 1 oz. You need  1/8 of the fill chamber for 4 gallons,1/4 for 8 gallons, 1/2 for 16 gallons, and 1 oz (full fill chamber) for 32 gallons. So just fill the chamber 1/8 for 5 gallons.
