TF 100 test came in today so I quickly conducted all of the test. I should mention it was early evening after a scorcher of a day. Pool is in direct sunlight and I had not added my usual chlorine yet. Here are the results
Had trouble with CYA test. When container was at the top of the container it was a little cloudy but dot still visible. Tested again and same results. Not zero but less than 20.
What do I need to correct first? I already added chlorine but do I then work on CYA or do I work on getting TA down. Wasn't sure which area to correct first. What is the order?
