High Alk Problem

If it was me, I'd try to get all of the "big three" raised up so that they are closer to balanced, and then stop dosing and let them fall on their own.

+1. Thats what i would do as well. 11dkh is a bit high but not dangerously high. I usually keep my alk around 10-10.5. Hope you get it figured out.
