Spa Calcium Hardness & Scale Inhibitor

If you have recently become the owner of a brand new hot tub or spa, you need to familiarise yourself with the water hardness or calcium 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.

 

So what is it you need to know - here's the basics:

  • Water needs to have a certain hardness level to it because soft water can be very corrosive,

  • Harder water can cause limescale.

  • Whichever side your waterfalls, you need to have a more balanced level.

  • Spas and hot tubs with acrylic finishes should have water with a calcium hardness level of around 100 to 250 parts per million

  • In spas and hot tubs with a plastic finish, the water calcium level should be between 250 to 450 ppm.

 

Whilst trying to find the perfect simplified answer with regards to increasing calcium hardness in hot tub water, you will also read quite a few variations of the product ranging from spa calcium hardness increaser, hot tub calcium increaser, calcium chloride flakes, hot tub calcium chloride, calcium builder, spa hardness plus and so many more, these are all the same products with varying names… 

Any form of calcium hardness increaser is fundamentally based on the chemical identity of Calcium Chloride which as per all the other names will increase water hardness in your spa water.

 

Managing your calcium levels in your spa water is highly important and combining this with correctly managing your total alkalinity and pH levels set the scene for your primary sanitiser to be as effective as it can be.  

 

Achieving the right water quality from the outset will indeed help maintain the inner working of your spa and depending on where you sit in the hardness level scale the action you take now will ensure the best possible longevity for your spa.  

 

Soft water areas will indeed require a calcium chloride hardness increaser or hot tub hardness increaser to ensure you minimize the corrosiveness of your water and on the flip side hard water areas will face the limescale build-up challenge, using a polyspun pre water filter that attaches to your hose and removes down to 5 microns of minerals in your water will help maintain your spa.
