CO2 Levels?

Hello everyone!
I've just embarked on the use of CO2 and am new to this forum and I have a question about CO2 levels in my 130 litre tank.
I use DIY CO2, KH is 60 ppm, PH is 6.8, GH (if needed) is 120 ppm.
Can anyone point me in the direction of a calculator to determine CO2 levels in there.

Thanks!

Just out of curiosity, what is the formula for calculating degrees of KH using PPM?

Divide ppm by 17.8. Same for GH as well, and multiply to go from degrees to ppm.

So what if you find you don't have enough CO2 even with 2 "2 liter bottles" of DIY CO2? I must be missing something..

You either need a better method of diffusing the CO2 into the water column or you have too much surface agitation or you just have too much tank for your CO2 generators.
