why else would they give us two lol?

when I started and was slow with the Hanna was using both vials. Now do the C1, add reagent, shake, hold the button to get the 3 minute timer started then done. Seen a video where you crease the packet to get a funnel helps to pour.

I wish they'd just increase the automatic off time to five or ten minutes. I also wish they'd use a method that isn't so finicky to tiny variables and would be more consistent.

Having said that the phosphorous ULR checker does seem to be pretty reliable for me. It uses the same process as the phosphate but measures phosphorous; then you do some simple math to estimate your phosphate concentrations.
