ph kh and co2

[panboy]

i saw a chart on the internet where u can estimate how much co2 u have by measuring ph and kh. however my ph is raelly higher about 7.6-7.8 and about at that ph it doesn't show what a good co2 level would be.

does this mean high ph lower the effect of co2?

Try here: http/www.csd.net/~cgadd/aqua/art_plant_co2chart.htm

Scroll down -- they have textboxes that will automatically calculate your CO2 if you type your pH and KH into it, or if you scroll a little farther, there is a chart that goes all the way up to 8.0. HTH.

great for the website, thats a great one, ive seen many with charts and explanations but this probably better well described than the others.
