For Those With Low pH

[jda]

I would suggest that you invest in a cheap co2 meter. This one at amazon is not expensive and can likely tell you why your pH is low.

I run a CaRx quite aggressively and with an indoor co2 of about 400-420, my pH never goes below 8.1 at the low. If it gets over 650-700, the pH will climb a bit and that is when I know that I need to open windows, even in the winter time. Just a few minutes with the whole house fan running in the winter can get me back below 500 ppm and the home cools down only a degree or two.


Those who are worried about their heater running more - compare the cost of a few cents of natural gas to a reactor, soda lime, shipping and all of that.

Anyway, take this for what it is worth to you...

Since you are running a calcium reactor. You could consider dripping sodium hydroxide to bring the ph up and also provide alk.

Kalk does a good job. But I also have a Co2 scrubber being controlled by a motorized 3 way ball valve wired into my Apex. Between all that, opening the windows every once in awhile and having plants to “clean the air” it’s pretty effective.

I don't have any pH issues, even with a CaRx. I was explaining how, and also a cheap tool to see where you are at.
