Are there reliable NO3 and PO4 alternates to Hanna testers? Honestly I hate the process. The reagent packets, the 2 minutes of shaking. I appreciate the Salifert titration method, but obviously want accuracy. That said, I would rather go through the Hanna process than do a color comparison chart. Thats useless for me. So basically, is there a reliable titration tester alternate to Hanna?
