I have the PS233 test kit & suddenly needed (don't ask) new powder for the DPD test. Needing it quickly, I ordered it from Leslie's Pools & got it in today.

The powder is finer & the scoop that came with it is smaller. Do I use their scoop & do the rest of the test the same & use the same 10ml of water?

Or do I use Ben's scoop & proceed as usual?
