To Much C02?

[blue130]

hi there, i have approx a 32 gallon planted tank with diy c02 and have a kh of 7 and a ph of 6.6 it has been like this for a while and the fish seem okay. but have i got to much c02 in the tank? have looked at some of these c02 charts and 1 says to much and the other says not enough? i know these are not the most accurate ways of measuring and that there is a lot of factors to adjust the results, 1 even says that i cannot overdose on diy? i have checked these results on several occasions and the result is always the same. any imput would be greatly appreciated as i am ripping my hair out!

There is no way you could overdose a 32gallon on diy CO2. Would be very hard.
Also, you are assuming that the carbonic acid (CO2 dissolved in water) is soley down the pH change when infact there are other things. The charts are useless.
Do the fish look fine? Are they acting drunk or gasping? If not, then it's fine. A pH of 7 to 6.6 is nothing much.
