So I guess I’ll ask it here because I don’t see an issue with your alk I only see an issue with your trident . On your fist post you show a pic of your graph. I asked you is you manually tested on July 6th the day alk went up to over 8.7 to verify if trident was off or if tank really at 8.7 from 7.7 in a split second which I’m sure is trident error. And as I said in your other thread which you did not reply to this is most likely a trident error from regents or sucking something up. Your question is why is alk dropping but it’s not dropping from where it was on july5th the day before the spike it’s just finally after days correcting itself from sucking something up
