Here is your handy dandy chart, (courtesy of Broomer5) that is hanging right near my computer.
pH 8.2
Alk meq/LAlk dKH Calcium ppm Calcium mM Ca++
0.00 0.00 360 9.00
0.50 1.40 370 9.25
1.00 2.80 380 9.50
1.50 4.20 390 9.75
2.00 5.60 400 10.00
2.50 7.00 410 10.25
3.00 8.40 420 10.50
3.50 9.80 430 10.75
4.00 11.20 440 11.00
4.50 12.60 450 11.25
5.00 14.00 460 11.50
5.50 15.40 470 11.75
6.00 16.80 480 12.00
6.50 18.20 490 12.25
7.00 19.60 500 12.50
So if your alk as you say is 12.5dKH then you are looking for a target of about 450 for your calcium.
clear as mud?
