AquaSPArkle Spa Hardness Plus is an effective product used for increasing calcium hardness levels within your spa water. Calcium hardness levels should be maintained within the recommended range of 100 - 200mg/l (ppm) to ensure that the spa and spa equipment is protected.
Ideal Calcium Hardness Range: 100 – 200mg/l
When the calcium hardness level is below 100mg/l water can become corrosive leading to damage to spa finish and spa plant equipment. Spa Hardness plus is used to increase calcium hardness.
- Before applying this product it should be pre-dissolved in a clean plastic container at a maximum rate of 10g per 0.2 gallons (1ltr) of clean cold water. Stir well to ensure the product is fully dissolved. Repeat application to achieve the total dose required – see table below for dose rates. It is recommended that the total treatment is split into three equal applications with a minimum of 1 hour between each.
- After pre-dissolving add the resulting solution to the spa with the filtration system in operation.
- Following the application the spa water may become cloudy so keep the filtration pump running continuously until it clears.
