pool 28000 gallons, vinyl FC very high, TA was almost 0. PH was VERY high, off the charts.
I just opened up my pool. Was very clear and blue. Shocked it a few times thought life was good.
I saw PH was high so I added PH minus. and it turned green, CLEAR green, in an hour.
went to pool store they gave me what I should do. I needed 42 lbs of sodium bicarbonate. I got that in good range.
I took chlorine tabs out as chlorine is off the charts. (But it does not smell strong at all, people have swam in it and no eye complaints or skin)
I am getting frustrated....Could this me copper?
Please help.... I have had a few pools in my time and NEVER had this occur.
