pH Increaser contains sodium carbonate
1kgs per pot
The ideal spa pH levels are between 7.2 - 7.6, promoting bather comfort, optimum chemical efficiency and protection of spa plant equipment. Test the pH of your spa water and if it is below 7.2, use pH Increaser to raise it.
Always adjust pH when the water is at temperature, as the heat of the water affects the pH reading.
