It is important to maintain the correct water balance to create the perfect conditions for you to relax in. We recommend that you follow the guide below in order to achieve this.

Calcium Hardness
It is important to achieve the correct level of calcium in your water, the levels of which will vary depending on where you live and where your water supply comes from. Soft water tends to be low in calcium and hard water tends to be higher.Every time you top up or refill your hot tub with fresh water you need to check levels of calcium.
The ideal calcium hardness level for a hot tub is between 100 -200mg/lIf the level in your hot tub is below this it could lead to corrosion damage. If you do find the level is low, then use Hot Tubs Hardness Plus to bring it up to the correct level.If the level in your hot tub is above this it can lead to the water appearing cloudy. As a result, calcium can be deposited on the tub shell, heater element, filter cartridge element and the pipe work within. To reduce this use Hot Tub No Scale to correct the level.

Total Alkalinity
This also depends on your water source and should be checked every time fresh water is added. The ideal Total Alkalinity for your hot tub is between 125 – 150mg/l If it stays between this it will prevent the pH of the water fluctuating. If the level falls below the recommend amount the water can become corrosive causing damage to the hot tub equipment. This being the case, we suggest using Hot Tub pH Plus to raise levels.
If the level is too high, the water can become poor in clarity and scale will form. To reduce this use Hot Tubs pH Minus.

pH Levels
It is essential you regularly check the pH of your hot tub water using Hot Tub Test Strips. The ideal pH range is between 7.4 -7.6, this is slightly alkaline which protects the hot tub and equipment. It also provides the most comfortable condition for hot tub users and has a good sanitising efficiency. If the pH level is below 7.4 use Hot Tub pH Plus to raise the level and if the pH level is above 7.6 use Hot Tubs pH Minus to reduce the level.

Sanitising of your hot tubs water is vital to kill bacteria and prevent algae growth. Levels should be checked regularly using Hot Tub Test Strips. You can use either Chlorine or Bromine to adjust the levels. Most people use Chlorine, preferring the smell to Bromine.

 

Using Hot Tubs Bromine is a very effective hot tub sanitizer. It comes in tablet forms making it easy to apply to the water.
The ideal Bromine level is between 3 – 6mg/l

 

Using Hot Tubs Chlorine is another effective hot tub sanitizer. It comes in granule forms which dissolve very quickly in the hot tubs.
The ideal Chlorine level is between 3 – 5mg/l

 

Oxidising
We recommend that you oxidise your hot tubs monthly using Hot Tub Non Chlorine Shock. This destroys odours and other undesirable additions such as perspiration, cosmetics and body oils.
By doing this monthly it improves the comfort and hygene for hot tubs users.
