I am at a loss as to what's happening. My cya is at 40 and I have had chlorine levels as low as 17 to shock and up to 40+ and the green water hasn't changed at all. The first 5 days of shocking I had the pool covered but it's uncovered and still no change. Ph at 7.4 but I have to add acid every 3 days to keep it there.
I've only ever added cya, muric acid and chlorine to my pool.

Welcome to the forum!

How are you testing? Can you provide a full set of test results from your own water testing kit?

Take care.

Do not worry about your TA until you are done with your SLAM and your water is back to maintenance levels of FC. Then as you add acid to lower your pH from 7.8 down to 7.2 your TA will drop.

If the pH rise is problematic, there is a process in Pool School to lower your TA. We can discuss that after the SLAM.

Take care.

I think because my TA is so high it isn't allowing my ph to come down. the chlorine isn't effective with my high ph. I'm looking in to how I can aerate with no handyman skills (building a fountain off of my return is beyond me)

Is the water green and cloudy, or a beautiful clear emerald green?

If it's clear but green, it's probably copper from algaecides.

So let me ask again.... how are you testing? And are you brushing and vacuuming as well? Chlorine alone will not eradicate algae, as it grows a protective slimy biofilm that needs to be brushed off.
