1. The kit did not come with a calibration solution so I will order one tomorrow. I should have thought of that, and Hach is SLOW on the shipping.
OK
2. mg/l=ppm yes?
Yes, they are close enough to be equal/. For us it is ~ 1.023 x ppm = mg / l
3. The low test is from 5-100mg/l (too low) and the high test is 20-400mg/l this means that for the high test each drop of titrate=1.12 dKH which seems to be a bit coarse. Should I be using a different test
If you dilute that 20- 400 by 2, then it becomes 10 - 200 ppm and 1 drop = .56 dKH. 2 meaning 1 part sample with reagent and add 1 part RO/DI water. So, it the sample was say 10 ml at normal testing you would do the 10 ml and then add 10 ml of RO/DI water to equal 20 ml and then titrate that 20 ml, where each drop now would equal 0.56 dKH.

So, I am working ahead and making lists of all that I need on hand. I just need a list of all that I should have onhand to test at the starting point. Obviously, PH, Ammonia, Nitrite.....
