Ok so I tested again this morning....
API 8.5
Salifert 12.5
tested the check solution which is labeled 7.3....
and got 11.5 *wonders if salifert tests the check solution with their test kits*
so if I subtract 4 from my 12.5 reading I get 8.5 which is what the API test reads
The second salifert test kit from the shop was off the charts...according to that one my dkh is over 16.
I hate test kits!
