I am aware the FC levels of greater than 10ppm will affect pH testing. And, one can dilute the pH test sample with distilled water in order to overcome the issue. My question is there any other reliable way to compensate for higher FC and pH testing?
1) Using a scale to adjust for the testing error? That is... if FC levels = XXppm greater than 10ppm, compensate result by X.XpH?
2) Adding two drops of the R-0007 (sodium thiosulfate) chlorine neutralizer prior to testing pH?
If I'm way off track (not uncommon for me), please let me know.
