AquaSPArkle Spa Hardness Plus - 1kg

In stock

AquaSPArkle Spa Hardness Plus increases the calcium hardness of hot tub water.

When the calcium hardness level is below 100mg/l (very soft water) the water can become corrosive leading to damage to the hot tub finish and equipment. The tub surface can become abrasive and uncomfortable for bathers.

Rough surfaces also increase the likelihood of problems with algae growth and make cleaning more difficult.

Hardness levels should be maintained between 100 - 200mg/l (ppm)

Use: Pre-dissolve AquaSPArkle Spa Hardness Plus in a clean plastic container at a maximum rate of 10g of product per 1ltr 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'.

NB When balancing spa water first adjust the Total Alkalinity and buffer the pH (this stops the pH value fluctuating rapidly). Next adjust the pH and finally, if required, adjust the Hardness.
