Last week for the first time Since May I brushed the floor of the pool and could see lots of green clouds being formed by the brush stroke. My understanding is that this is algae, I poured 10 litres of liquid chlorine into the pool last night and waited 24 hours to test the water while keeping the swg on super chlorinate. I tested the water today and the results are below. the water is still cloudy but the results show no CC... I am wondering what the problem could be?
CA: did not test as no stabilizer was added this season to the water.
