I think your 14.7 reading is a testing error.

The reference solution is to check that you are doing the basic test correctly. Run the ALK test, but using the reference solution instead of tank water. If you are doing the test correctly, then you should come within 10% of the setting that is printed on the reference solution bottle.

If you are close, run the ALK again with your tank water. If you still get 14.7, the stop dosing the ALK part, just the CA part (as long as the CA test isn't higher than 450.

Targets are CA - 400-450, ALK 7-11 DKH. A good balanced match is 420/10 or 450/11
