I'm getting more into planted tanks. Can you use the pH and KH chart to estimate CO2 while using Flourish Excel?
On Seachem's website, it states that Flourish Excel does not alter pH levels, do would using the pH and KH chart still work to estimate CO2 levels? If not, how can you know how much CO2 is in your tank?
