I've been battling phosphates for 2 weeks 0.22! till I realize that the last 2 boxes of reagents for my Hanna phosphates checker have brown powder in them and not white as usual, so I ordered a new pack of reagents and my measurements where 0.02!
I threw away 3 kg or Rowa, which are really expensive in my corner of the world and 2 boxes or reagents!
