STAIN AND SCALE PREVENTIVE MAINTENANCE
Maintain pool water in the pH range of 7.2 to 7.6, total alkalinity at 100 to 150 ppm and calcium hardness at 100 to 275 ppm. If pH falls below 7.0, serious corrosion problems may result. For best results, use Stain Rust & Scale Control in the evening with the pool pump and filter operating overnight.

Add four to six (4-6) ounces of Stain Rust & Scale Control per 10,000 gallons of water every 4-5 days by premixing into plastic pail of water and then dispensing solution at deep end of the pool.
Cloudiness accompanied by white flakes may appear indicating that the product is working, the cloudiness will eventually disappear.

Start Up Dose:
Add 16 oz. of Cell Extend per 10,000 gallons of pool water directly to the skimmer while pump is running. If the water contains over 400 parts per million (ppm) calcium or 0.1 ppm copper or iron, add 32 oz. per 10,000 gallons of pool water. After Cell Extend has been added and the pool is filled, filter and circulate the water at least overnight before adding chlorine or other pool chemicals to allow this product to disperse and work effectively.

Monthly Preventative Dose:
Add 4 oz. of Cell Extend per 10,000 gallons of pool water directly to the skimmer while pump is running. Always ensure that the water is properly balanced before using this product.
 

Directions for use:
This product is best used for the prevention of metallic staining and associated colored water. It sequesters and chelates the material causing stains and scale and holds them in solution. If stains persist, they may be old ones requiring complete cleaning of the walls, or stains of an organic nature. Dissolved metals and minerals (such as Iron, Calcium, Manganese, and Magnesium) in pool water and corrosion of metal pool fittings will often cause staining and/or scaling. Do not let pH of pool water fall below 7.0 or serious corrosion problems may result. For prevention of metal stains, colored water, and scale it is also essential to maintain pH at 7.2 to 7.6, total alkalinity at 100 to 150 ppm, and calcium hardness at 225 to 300 ppm.

Initial Use
1. Before using this product adjust pH to between 7.2 to 7.6
2. For best results, use this product in the evening with pool pump and filter operating overnight.
3. Add 16 ounces (1/2 bottle per 10,000 gallons directly to the pool or premixing into plastic pail of water first. Dispense solution evenly around the pool with the system running. DO NOT pour into skimmer. Continue to run pump for at least 24 hours.

Stain and Scale Preventive Maintenance
1. After INITIAL USE, repeat application at the rate of 4 ounces per 10,000 gallons every two weeks.
2. In pools with a known metals issue, dose at the same level of 4 oz. per 10,000 gallons but on a weekly schedule.

Winterizing
1. Apply at the rate of approximately 10 ounces per 10,000 gallons of water by evenly dispensing as above.
2. Allow pool to operate for a minimum of one hour to thoroughly mix the product into the water prior to closing.

Hard Water Note: In areas with hard water where calcium hardness exceeds 400 ppm, it is advisable to double the dosages listed above. However, DO NOT increase the dosages more than double for any one application.

DIRECTIONS FOR USE:
Maintain pool water in the pH range of 7.2 to 7.6, total alkalinity at 100 to 150 ppm and calcium hardness at 100 to 275 ppm. If pH falls below 7.0, serious corrosion problems may result. For best results, use Metal Out Plus in the evening with the pool pump and filter operating overnight. Add sixteen (16) ounces of Metal Out Plus per 10,000 gallons of water by premixing into plastic pail of water and then dispensing solution at deep end of the pool. Cloudiness accompanied by white flakes may appear indicating that the product is working,
the cloudiness will eventually disappear.

MAINTENANCE TREATMENT:
Follow all steps outlined above. Every 4-5 days, add two (2) ounces of Metal Out Plus per 10,000 gallons of pool water, to prevent stain and scale formation. Note: In hard water areas where calcium hardness exceeds 300 ppm, it is advisable to double the dosages listed above. However, DO NOT increase the dosages more than double for one.
 

Normal:
Use 16 oz. RESIST per 10,000 gallons of pool water. For hard water, (over 200 ppm), high iron, copper or manganese content (over 0.1 ppm), double the initial dosage (32 oz. per 10,000 gallons).
Add RESIST after the pool has been filled. Filled pool should then be circulated overnight before adding chlorine or other pool chemicals to allow RESIST to react with and prevent precipitation of minerals in fresh fill water.

Tips:
Resist should always be added when a pool is initially filled or when fresh water is added, because most fresh water will contain some stain and scale producing minerals.

 
Removal of stains and scale:
Apply 16 oz. of Staintrine per 10,000 gallons of pool water capacity as close to the affected area as possible.

Tips:
Follow Staintrine treatment with weekly doses of Resist. Resist prevents metals and minerals from staining pool surfaces.
