CO2 chart (KH to pH relationship)

[Angry the Clown]

Hi All,

Here in central Texas, the water comes out of the faucet in the form of liquid rock!

I have copies of various CO2 charts that show the relationship between KH and pH. However, there always seems to be a jump from KH 10 to KH 15. Does anyone have a link that would show the relationships for the numbers between 10 & 15? I know that I could estimate, but I would prefer to have a more exact figure for my KH of 11.

Thanks!

This link has a calculator. There is also a windows applet you can download.

Hope this helps.

If you prefer, this is the calculation that all the charts and calculators use:
CO2 (in PPM) = 3 * dKH * 10^( 7-pH )

Another way to deal with reading the CO2 of your liquid rock, would be to build a drop checker like the one listed in the sticky at the top of the forum.

Once again, YOU GUYS & GALS ROCK!!! I am going to try to get a drop checker off eBay to get more accurate readings. Thanks again!
