Total alkalinity represents the waters buffer capacity to resist changes to the pH level.
Total alkalinity (TA) Total alkalinity is a measure of the amount of alkaline substances in the water. The guideline for total alkalinity (TA) is approx. 60 – 120 ppm.
Total alkalinity
| Min (mg/l): | 60 ppm |
| Max (mg/l): | 120 ppm |
| Tested: | 1 time/month |
A low TA makes the water aggressive and the result can be one or more of the following::
Total alkalinity (TA) is increased with sodium bicarbonate. The TA value is a process that should not be accelerated. Add small amounts sodium bicarbonate every four days until the correct TA and pH value has been reached.
A high TA makes the pH difficult to adjust and the result can be one or more of the following:
Total alkalinity (TA) is reduced with sodium bisulphate (pH-minus). To reduce the TA is a long process and can take several weeks. Add small amounts sodium bisulphate every four days until the correct TA and pH value has been reached.
