I've pretty much always dealt with C02 in a planted tank with other livestock (fish, shrimp, etc). I am setting up a high-light tub with pressurized C02 and the misting method to try to grow some UG.
So, basically, I want the C02 ppm on the High-side. Does it matter how high the C02 is? 30ppm? 50ppm?...???
In other words, in a plant-only tank--is there such a thing as too much C02?
Thanx!
