Hardness & Scales
If you have recently become the owner of a brand new hot tub or spa, you need to familiarise yourself with the water hardness levels in your area.
Water naturally has a certain level of hardness, which essentially means the volume/percentage of minerals, such as magnesium and calcium to name two, dissolved into it. In the UK, you will find a wide range of hardness levels from very hard in some areas to very soft in others and everything in-between.
Water needs to have a certain hardness level to it because soft water can be very corrosive, while harder water can cause lime scale. Whichever side your water falls, you need to have a more balanced hardness level.
Spas and hot tubs with acrylic finishes should have water with a calcium hardness level of around 100 to 250 ppm, that is parts per million. However, if you have a hot tub or spa with a plaster finish, the water calcium level should be between 250 to 450 ppm.
