So I’m having an issue with my Hanna test. If I’m using the test correctly then right before lights on my c02 was 30ppm and now at the midway point it’s 11ppm. I’m not sure how that’s possible. Also the direction show putting the solution into the syringe with the long thin tip on it however when I try that the syringe cannot suction up the solution. So I’ve been sucking up the solution without the tip then adding the tip. Any solution left in the tip after I get faint pink I just suck back in before reading the number. Am I doing this wrong? Ugh! Really wanting to dial this in before this algae destroys my sensitive walichi
