Water TechniX Calcium Hardness Up 2Kg collections_pool-pumps it captures up to twiceWhat does it do? Increases calcium hardness to prevent pool surface etching and equipment damage. When your calcium levels are low, your pool water becomes AGGRESSIVE and it will pull calcium from your surfaces and will cause calcium build ups. How does it work? It uses high purity Calcium Chloride (990g 1000g) to safely boost calcium levels. How is it applied? Test your water, then add approximately 100g 150g per 10,000L to raise hardness by about 10
