pH is an important aspect of water chemistry for spas and swimming pools. pH Plus is essential to keeping your pH levels in check so that your spa or pool stays healthy!

This product not only controls the acidity level but also helps to neutralize chlorine odours in your water’s chemical balance, so it smells fresh every time you dip into them!

Why is it important to balance your pH level in your hot tub or pool?

  • It’s important to understand that pH is a measure of how acidic or alkaline water is.
  • ClearSpa pH Plus – Sodium Carbonate will bring the pool and spa into balance and create an environment where calcium, phosphate, and other minerals can be dissolved more easily.
  • If your pH level isn’t balanced, you could end up with cloudy water, skin and eye irritation, slipperiness, soapy water feel, or scaling.
  • The right pH level for ClearSpa is between seven point four (seven-point-four) to seven point six (seven-point-six).

It’s also important not to allow your pH to go too high:

ClearSpa has put together a great little read regarding high ph levels and also some great additional information regarding why Total Alkalinity is so important in your pH balancing journey

How to Use


1. Use a test kit to determine the pH reading, the ideal reading is 7.4 – 7.6, if the reading is below 7.4 use pH Plus to increase the reading.
2. To increase the pH dose at the rate of 10g per 1000lts of water.
3. If the Spa or Hot Tub water is up to temperature (above 30°C) add the pH Plus directly to the water with the circulation on. If the water is cold then pre-dissolve pH Plus in a clean container filled with clean warm water and then distribute around the surface of the water.
4. Re-test the water after 30 minutes, if the pH still needs to be increased follow steps 2 and 3 again.
5. Only add pH Plus in stages and always re-test after additions.
6. If you experience any difficulties please contact your dealer.
