I have a 18 x 36 inground pool. My chlorine lebel is 2.7 but the acid level is 80. Is this 80 too high? If so what do I do to get it down.
I have had my pool for 30 years and only drained it 1 time and that was when I had the bottom concrete redone.
I use 3 inch trichlor tabs in auto chlorinator.
I have never had this problem in 30 years until NOW.
My water is clear and I have never had algae in my pool.
