1. When performing the TA test do we stop when the color first turns pink or when it turns fully red?
2. When performing the CYA test we want to keep going until the entire black dot (all visibility, all traces) is no longer visible correct?
3. When lowering TA can I add water, if low, with the nozzle on a fine spray to aerate?
4. I live in Las Vegas with the temp well into the 100's. My CYA is a little under 40. Would it help chlorine consumption if I raise it a bit?
Any help appreciated! Thanks in advance.
