Dinoflagellates - How to Raise PH

[Werbo]

So I tried the Aquavitro Balance. It does raise the PH but is not very economical as I went through a $13 bottle in a day.

160G total water
My dKH is now at 9.6.
CA = 420
MG = 1400

Before work my PH was 8.1. So I bumped it up with 100 ml of baked baking soda (aka Rndy's 2 part) and 4 cups of limewater (dissolved kalk) to get it to 8.5 before going to work. Came home after work and it was back down at 8.1. This is turning into a full time job. I really don't wanna be driving home on my lunch hour.

Will a kalk drip work to keep it at 8.5 overnight and during the workday?

This is the first time I have played with raising PH and trying to keep it at a consistent 8.5 for a week straight.
Any input would be appreciated.

Thanks
