Please help. I've been reading for more than an hour and haven't found the answer to my specific problem. First let me say that I have an natural unfinished gunite/concrete (not sure if there is a difference in those 2 terms but in the 3 years I've owned this house I've heard both being used to describe my pool), IG pool which is surrounded by trees. Even when it is crystal clear it appears green. I've always assumed it was the fact that there is no finish to the pool floor and the water refelcts the green surroundings.
For the past week I have had green cloudy water, can't see the bottom on the deep end. My results as of a few hours ago are:
FC 1, TC 1, pH 7.2, TA 110, CH 250, CYA 20.
I know that the CYA being low will affect the chlorine so I think I need to do something about that before I dump in a gall or two of liquid chlorine. Please advise on whether or not I should be bringing up the CYA before shocking? Also, I'm a bit concerned about the pH, although it's in range I think it's a bit low. Thoughts?
I so appreciate any advice. Thanks
