DESCRIPTION

Pool & Spa Hardness is specifically formulated to raise the calcium hardness of water in recreational facilities. Low calcium levels can lead to corrosive water that damages pool surfaces and equipment. By maintaining the correct hardness balance, this product protects against costly repairs such as etched plaster and stained finishes.

APPLICATIONS

Used to correct calcium deficiency in all types of pool and spa surfaces. Ideal bathing conditions require a pH level of 7.2 – 7.6 and total alkalinity of 80 – 150 mg/l. Maintaining these levels ensures that all other pool chemicals function at peak efficiency while providing a comfortable environment for swimmers.

DIRECTION FOR USE – PRODUCT DOSE

Add Pool & Spa Hardness Increaser at the rate of 100g per 10m³ to raise calcium hardness by 10 mg/l. Dissolve the granules in a clean container of water first, then pour slowly around the pool perimeter. Keep the pump and filter running during application to ensure effective circulation. Re-test and adjust as necessary.
