Hi. Been a while. I have had great success with TFP. Thank you all!
I had a slight haze to my water and it just didn't seem right. Even though FC and CC were fine, and I could pass the coin test, I took it to SLAM level to try to determine if I had a chemistry or a filtering issue. I passed OCLT 2 nights in a row. So I'm good, right? I kept FC up again tonight for a 3rd OCLT.
However, I turned on the pool lights tonight and there was a slight yellow tinge in my water noticeable mostly in light reflection on opposite walls and around the white stairs. Is this chlorine? An optical illusion? Whatever, it is new to me.
Current results (tonight's except CYA not tested in over a week, pH not tested in 4 days)
