Phosphates Scenario followed by a question: I've been using the Hannah Phosphorous ULR checker and multipling by .003066 for the last 2 years. I just ordered a new batch of reagent. My old batch just gave me a reading of 16 which puts my phosphates on par with my average readings in the past. 0.049
Well, I did a second and third test with the new batch of reagent...... they yielded a reading of 1 and 0 respectfully. 16 on my old batch, 0 and 1 readings on the new batch of reagent. Anyone else ever deal with something like this?
