Description
Heavenly Hot Tubs Total Alkalinity Increaser – 1kg helps raise low total alkalinity in your hot tub or spa. Keeping alkalinity balanced helps prevent sudden changes in pH, making your water easier to manage. Test your water first, then add this hot tub total alkalinity increaser according to the instructions on the pack.
Total alkalinity helps stabilise the water’s pH level. When alkalinity is too low, the pH can fluctuate rapidly, making the water more difficult to balance and potentially causing discomfort, corrosion or damage to spa components.
Correcting total alkalinity before adjusting the pH makes routine water care easier and helps maintain stable, comfortable bathing conditions.
Test the water before use and add the product gradually, following the dosage instructions on the packaging. Allow the water to circulate before testing again.
Always read the product label before use. Never mix hot tub chemicals together.
