thank you for the feedback. I have ordered a FAS DPD test kit and will report back on the results.
Automating sand filter backwash function, is it possible?

What were you using to test previously?
Don't forget to get a CYA test (cyanuric acid)
Hi All I have now completed testing with FAS DPD kit my situation is as follows
FC 9.5
CC .5
CYA 25 (using test strips)
I did an overnight chlorine loss test and the level decreased overnight from 9.5 to 9.0 ppm I took a reading at 7pm after sun went down and at 7am sun had been up for 30 min but pool was shaded from house

The FC loss is fine. But you have no idea what your CYA level is for your FC level going forward.
