Hi..
35-42 ppm CO2 = 35-42 mg/l is to much.
15-20 ppm CO2 were o.K.
What does anyone think?
I think fish is the decisive factor.
30 ppm seems to be the norm these days, many people run much higher
without any ill effects.
^^
That sentence makes me feel becoming old..! ;-)
I keep mine around 35 ppm, which seems OK.

I guess it all comes down to who you believe:

I get too much growth for my liking actually.
Really? :-)
Not to mention too many large fish for a 15 gallon.
I agree with you.
