I opened the pool two weeks ago. The water was so cloudy/bit green so I shocked it (it is all good now). At the time, I only tested/added salt and bleach to the shock level. I didn't add any CYA. I just assumed it at the good level when I closed the pool in the last winter. I only tested/added CYA later when the water seemed clear, CYA level almost zero.
Would it be accurate if testing CYA when water is cloudy? Should I test/add CYA before start shocking it?
