Yes, you can certainly raise your alk alone to get the levels you want. After reaching desired levels, then use your calcium reactor to maintain both, or 2 part or kalk or whatever method you use regularly.
I have been dosing Alk alone for the past 2 weeks as my calcium levels were too high for my liking (460 plus) and my Alk was at around 7. I turned off my calcium reactor 2 weeks ago to let the levels naturally drop on its own and have been dosing Alk daily to maintain it at 7. My calcium levels are now at 440. As soon as my Calcium drops to 420, I will put my calcium reactor back online and cease dosing Alk daily.
Hope this makes sense.
