Pure-Spa Hardness Increase
£13.12

Pure-Spa Hardness Increase - 1kg

The ideal spa calcium hardness levels are between 100-200mg/l (ppm), promoting 'balanced' water and protection of spa plant equipment. Test the calcium hardness level of the spa water and if it is below 100mg/l (ppm) use Hardness Increaser to raise the level. 

Instructions:

1. Pre-dissolve the product in a clean plastic container at a maximum rate of 10g of product per 0.2 gallons (1lt) of clean cold water. Stir well to ensure product is fully dissolved. Add the resulting solution to the spa whilst the pump(s) are turned "on", preferably near to the water inlets to aid distribution.

2. The total amount of Hardness Increaser required can be calculated using the dosing table below. This total should be split into 3, adding one third every 30 minutes.
