Newbie here and trying to get my pool in order. I recently got everything i need to do testing at home and I'm curious about the DPD powder.

The TF100 test video says to use "a large scoop" of the powder into the water sample. How large are we talking about? Heaping? Even with the scoop? How much of a difference is it going to make in my numbers?20200729_160836.jpg20200729_160851.jpg
