Pro Poly-Guard Polyphosphate Anti-Scalant (Liquid) 1 gal

Applications
Poly Guard should be applied by using a chemical metering pump. Dosage rates can be determined by the calculations at the bottom of this sheet, or by contacting Pro Products.

Features and Benefits
Poly Guard is designed to keep iron and calcium suspended in water. It reduces reddish iron stains, which are formed on driveways, walkways, buildings, plants and shrubbery during irrigation. Poly Guard helps in corrosion control of pipes. It reduces lead and copper leaching and forms a protective film on the piping.

Poly Guard dosage calculation :
30 Gallon Tank 1 Gallon per Day Feed Pump**(720 hours of sprinkler operations between refills) **If a larger pump is used, divide the gallons of POLY GUARD required by the gpd of the new pump. For example, a 3 gpd pump would require only 3 gallons of POLY GUARD in the tank (9 gallons of POLY GUARD/3 gpd pump).

Instructions :
For each 10 gpg of hardness, increase the POLY GUARD dosage at the rate of 1 ppm Iron as shown on the chart.For each 1 ppm of manganese in the water, increase the POLY GUARD dosage at the rate of 1 ppm Iron as shown on the chart.
Add proper amount of POLY GUARD to the tank. Add sufficient water to the tank to bring the level in the tank to 30 gallons. Use municipal water for filling the tank whenever possible.
