30 ppm is what most of us use. This is 4 dKH.Probably should get some solution from Sumo.
Just don't know which ppm

1 dkH = 17.9 ppm CaCO3... so buy the 71.6 ppm one?... hahaha

Yes, 1 dkH = 17.9 ppm. Thus, you want to get the 71.6 ppm or the 4 dkH reference solution...hmmmm... our numbers do not agree with eachother... what is the deal?
