Available to hot tub owners in the UK only WATER HARDNESS INCREASER

buy test strips for hot tubsWhat ever sanitizer you use, the Total Hardness should be tested on first filling your spa and thereafter at monthly intervals. As water evaporates from the spa the minerals get left behind and become more and more concentrated, consequently the hardness of the water in your tub will increase over time.

Hot tub water with very low total hardness (very soft water) can cause etching to occur on the tub surfaces which will 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)

Always adjust the Total Alkalinity and the pH before the Hardness.
