Description
Calcium Hardness Increaser is a product used to increase the calcium hardness level in hot tub water. Calcium hardness is a measure of the amount of dissolved calcium in the water.
Why is calcium hardness important?
Protects your hot tub: If the water is too soft (low calcium), it can corrode metal parts and damage the hot tub’s surfaces.
Comfort: Balanced calcium levels contribute to a more comfortable and enjoyable soaking experience.
Water balance: Calcium hardness plays a role in maintaining overall water balance, which is important for effective sanitation and preventing issues like scaling or cloudy water.
Instructions:
1. Take a calcium hardness reading with a quality test kit. The correct reading is a minimum of 250PPM (mg/l).
2. Dose at a rate of 10g of Calcium Hardness Increaser to 1,000 litres (220 gallons) of water. Each dose will raise Calcium Hardness by approximately 10PPM (mg/l) and add no more than 50g at any one time.
3. With the circulation running, sprinkle the product directly to the water; do not pre-dissolve.
4. Bathing may recommence when all product has been dissolved.
