pH has dropped to 7.2 from high of 7.5. Is this fluctuation normal? I thought that by adding chlorine pH would increase?

Do specific trees make the pool more acidic? In the garden I use Oak leaves to make the soil more acidic. Oak tree shadows the pool in the AM.
I am still cloudy, but water is blue.

POP is still low. I opened pool to family. Waiting on K2006 test kit to arrive. I want to test CYA so I know how high I can run FC. I am on the slow and steady program to prevent copper staining. How long does this slow and steady last? Copper be D&mned! We want clarity!

Called pool store to see if I could get a test to monitor FC at levels of 10-15 ppm so I could shock (POP is .03ppm) and maintain levels for 3-5 days to finally get to clear. Pool store person told me that
1) You will burn the liner!
2) You have phosphates!

Both of which I know to not be true based on the info I learned about here. Hooray Science & Thanks PF crew.

I imagine any issues I will have with the liner are due to not keeping the pH above 6.8 (which is where it was when I opened).

ALSO Wife said she was impressed that the water looks as nice as it does considering that in some years the water never looked as good as it does now.
