Was just surfing the net looking for the levels of CO2 ppl have in planted tanks.
Now most say that 10-40 mg/l(ppm) is about good for plants, some say that for fish 5mg/l is maximum or they die, some say they have 160 mg/l and fish are ok(when i say fish i don't mean a certain fish but fish in general, from neons to discus to whatever.)
Now i just did a test in my 92G and i have around 44 mg/l, plants are ok, fish are ok BUT my plants do no pearl. And i know they do pearl when they have nuff CO2.
Anyone has any imput on this? What is your CO2 lvl?
