How can you fix a green pool?
So i am working with pools for like 3 months
2 days ago someone told me to fix his green pool,size 70m3
First day
I adjusted the PH 8.2 to 7.2 and added chlorine 2kg while the pool had 0
Also the pump worked for some hours
Second day
Back wash,water was full green for a lot of time
Then i vaccumed and backwashed again,the water wasnt very light green while the backwash so i guess i didnt vaccum too many algae
Added like 3kg Chlorine while the test was showing that the pool has more than 4-5 chroline already from previous day(suppose it wasnt free chlorine)
And i left the pump working untill tommorow
So from now on what i do?
