Hi, I've read her for a while but have never posted and now I'm at the end of my rope. So here I am. I've read pool school a couple times and I'm still perplexed . We have an inground pool we've had for eight years now. This year it seems to be one thing after another and the pool still isn't clear. We opened it about three weeks ago. We tested the water and thought we got everything situated but the water is still cloudy. So, while it's still not the green swamp it was when we opened it, it's still not to where it should be. This is even after we changed the sand in the filter (It had calcified and the water wasn't filtering right). So, I'm posting my test results below and any guidance would be appreciated.
FC - 4.5
CC - 1
pH - 7.6
TA - 180
CH - 560
CYA - 30 (I filled tube and could still see the dot)
Thanks in advance for all of the help.
