In addition to the above guide, consideration should be given to hydrochloric acid (It does not increase
sulphate in pool water) when high bathing loads are expected. Consideration should also be given to dual
dosing with CO2 and acid if the alkalinity of the water is unstable.
In order to maintain the highest standards, Topline reserves the right to alter specifications without notice.
