How are you reading your elos test kit? Is it 1 drop=1dkh or 1 drop=.5dkh .
I followed the directions on the paper 1 drop= 1 dkh and had a reading of 15 dkh (salifert was reading 7.8 ) It took days for my alk to drop to 10 dkh and then someone on here posted that the instructions on the paper are wrong you have to follow the directions on the card which reads 1 drop = .5 dkh my alk was actually at 5dkh and the elos and salifert test kits agree with each other
