I decided to do a series of testing. I was concrete on my methodology so I decided to try another batch of reagent..well reading were even higher! As I then wanted to pull my hair out (what's left anyway). In complete frustration I tested every water sample from tap to tank! @ this point I am sure some know the one thing I did not do FIRST...sample distilled water to see if any PO4 value obtained
You see I failed a basic procedure of a meter (verifying its accuracy ) my Chem Prof would blow a gasket!
***important rule of thumb...if readings seem off then check w/ a reference!!!***
I'm not sure I would even trust regular distilled water that was transported in a non-lab grade container. I recall theories about plastic containers leeching phosphates.
