Natural Chemistry Pro Series Stain and Scale

Initial Dose:

Add 32oz per 10,000 gallons to the pool water evenly around the edges. if water hardness level is above 400 ppm (parts per million), metal readings are above 0.5 ppm, or if being used during start-up of a new plaster pool, wait 24 hours and add a second initial dose.

Maintenance Dose for Scale Control- Monthly:

Add 5 oz per 10,000 gallons of pool water per month.

Maintenance Dose for Metal Control- Weekly:

Add 4 oz per 10,000 gallons of pool water per week.

Do not add product within 2 days of adjusting calcium hardness or during a full pool acid bath.

For new, remodeled or refinished pools:

Add 1/2 gallon of product per 10,000 gallons. Add product to the pool water evenly around the edges after the pool is full to reduce the chance of plaster dust formation, scaling, and metal staining. Balance pool water as needed (wait two days before adjusting calcium hardness).

Do not exceed recommended dose.*

* Note: Cationic polymers used in many clarifiers, flocculants, and polyquat algaecides should not be dosed to swimming pool water at the same time as metal control products. Cloudy water, precipitation and reduced product effectiveness may result. Wait 24 hours between additions.
