Hot tub maintenance won’t take up too much of your time once you’re up to speed. Read our complete guide to hot tub maintenance now. Test your spa’s Total Alkalinity once a week as part of your hot tub maintenance routine, add a few scoops of chemicals if they’re needed, and then finish off by adjusting the pH.

Once your spa’s Total Alkalinity is in balance, test its pH and then use pH increaser or decreaser to get that within 7.2 and 7.6. If your spa’s TA is too high, it’s pH levels will be sky high and just about impossible to keep below 7.6. If it’s too low, the water will be far too acidic and difficult to bring up to 7.2.

Your hot tub’s Total Alkalinity and pH levels are both closely linked. Each time you change one, the other is affected as well. is 2 molar equivalents because twice as many H + ions would be necessary to balance the charge. The total charge of a solution always equal zero. [8] This leads to a parallel definition of alkalinity that is based upon the charge balance of ions in a solution. are affected by changes in pH, temperature, and pressure. By isolating the conservative ions on one side of this charge balance equation, the nonconservative ions which accept or donate protons and thus define alkalinity are clustered on the other side of the equation. Calculate the amount of baking soda needed to raise the total alkalinity level so that it’s a minimum of 80 parts per million.

These compounds attract and release Hydrogen ions, which neutralise acid in your spa’s water and increase its pH level. Why is your hot tub’s Total Alkalinity important? If your hot tub’s Total Alkalinity (TA) isn’t within a certain range, the sanitiser you add to it won’t work properly. Blue Horizons Total Alkalinity – 5kg’s – Total alkalinity is a measurement of the waters ability to resist pH change.If your spa’s Total Alkalinity is too high, its water will be too alkaline. As well as stopping your sanitiser from killing bacteria as effectively as possible, alkaline spa water will also:
