Topic: Duel Feed Auto Pot High PPM

Using Duel Feed Auto pot system. Following chart to the T as far as chems to water however the PPMs seem to always be higher than what is listed on the chart. As high as 1600 ppm instead of 1050 – 1150This started at PK spike entry.Any reason for this? Water ppm is checked before chems were added and was at a low 50.
