It depends on how old you test kits are. Both of these test kits have changed in the last 4 or 5 months.
DKH used to be 1 drop per DKH to 5ml and recently changed.
I just bought a calcium test kit a couple weeks back and now its different then my last one. It has basically two kits in it one of the regents is 1 drop for 25 PPM calcium and the other regent is 1 drop for 10 PPM. They did this so you can get a more accurate reading.
So it would depend on how old the test kits are and hom long they sat on LFS shelf.
