I have had my tank set up for well over a year and a half. I have been tinkering around with DIY C02 in coke bottles and a DIY CO2
From what I had read in my KH
test kit and some things on the net, I found that you can use the KH
readings and PH results to measure the amount or get an estimated amount of CO2
in the water.
So, the other night I started testing before adding my new C02 diffuser. I had a 40 ppm KH
buffer and a 7.6 ph. I added the diffuser and then next day my ph went down to 7.4. The next day it was down to 7.2. I, out of curiosity, measured my KH
again and found that this had dropped as well. It was now at 20 ppm
I was under the assumption (and we all know what assuming does) that the KH
would stay the same. Is this not true? Or, am I just on the wrong track measuring my CO2
levels.? Please help....
