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 limescale. Whichever side your waterfalls, 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, which 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.
 
SpaChem ™ produces a number of different water hardness increaser products as well as a few scale removers too. They are available in various sizes, so you should be able to find the correct volume for the size of the hot tub or spa you have and can be delivered anywhere in mainland UK and Ireland.
