Green water indicates the presence of algae. The causes can be multiple:
Insufficient water circulation: check the filtration time.
Insufficient chlorine production: check the production rate, the condition of the cell, the salinity of the water (5 kg/m3) and the proper operation of your chlorinator.
An unbalanced pH: stabilize it between 7 and 7.2
Stabilizer level: a stabilizer level higher than 50 ppm will block the effect of the disinfectant produced by the chlorinator.
Pool attendance: the greater the attendance, the greater the demand for chlorine. Consult the calculator for chlorine demand.
Limescale (TH) rate too high.
Water temperature: a high temperature will require an increase in the filtration time and consequently the electrolyser’s operating time. See filtration time.
