On my 90 I've been using a Kalk Reactor. Now that I've started getting some pretty good growth, it seems I might be going for a Calcium reactor as well. I've tried 2 part in the past, but I did it somewhat half assed. I used the Aqua Lifter pumps instead of something more exact. The mixing up wasn't too bad. One thing you might do to fix the CO2 issue is to pull air from outside into an oversize Skimmer. I don't like the idea of solving low Ph through Kalk, you're treating a symptom not the problem, which is not enough Oxygen and too much CO2.
