Question to Mastertronic users

[RSNJReef]

Hey Guys,

So I have been using the fauna Marin notrate test reagents for testing my nitrates for some time now but wanted to switch back over to using the API notrate test reagents. I have the updatted stir rod (the bigger one) for the reagent 2 bottle, but trying to figure out if I need to run the api or the api-s profile.

Does anyone know which one is for the larger stir rod?

Thanks guys!!

Larger stir pill with newest firmware, use API-S
