Normally i add Pool Shock every 5 Day's ore so 0,1g per 20 Liter that's maybe 1ppm know i realise that the Temps are high so the Chlorine evaporated quicker is that ture? I have ppm test stips they showing me after 1-2 day's 0,5ppm so i need to add more Pool Shock maybe every 2 Day's when the Water is higher in temps?
