You can't use that chart/calculator to calculate the amount of CO2 in an aquarium. Chuck explains why in that same link.Just got back home and tested......
I have a Ph @ 6.5 and a dKH @ 4degrees.
Gives me 37.947ppm Co2 in tank which is high.
Now what? De-gas with airstone?
Your actual CO2 level is actually lower than this.Gives me 37.947ppm Co2 in tank which is high.
Correct. A "4 dkH" result from your tank water can be due to a combination of other buffers (not just the carbonate buffer). As the pH/kH/CO2 relationship works on the basis that the only buffer is carbonate/bicarbonate, you cannot use your tank water in your drop checker, even if it is "4 dkH".Allright so if my tank water is @ true(or tested true) 4dKH....Then I can't use that water as the solution in the checker because of the false readings due to phosphate and misc buffers.......Right?
I'm kinda liking this hobby more and more!
