OK I have a TF 100 and while testing the CYA I am looking directly down the tube, I cannot make the black dot dissappear. I just want to make sure I am looking at it right before I start adding stuff. Also while im here, my readings.....
Chlorine 1 ppm
I plan on adding liquid bleach using the pool calculators recommendations and water conditioner for my CYA. Does this sound right?? Or will the bleach raise my CYA also???
