o2 vs co2

[silvershark]

ok so you get air pumps to "inject" oxygen into the tank by creating water movement at the top of the tank as the water at the top is oxygen rich, thus mixing it up.

AND you get co2 pumps to increase the carbon dioxide levels for healthy plant growth.

isn't one gonna counter act the other? and also i heard the there are specific times of the day the each should be used as plants absorb oxygen during the night, is this true?

yes but most often if not always 02 will win because c02 is so hard to diffuse into the water yet so easy to loose.

so basically injecting c02 into a tank while you have a lot of surface agitation occuring would be a bit pointless since you will be loosing c02 concentrations

hmm for me personally i dont switch off the c02 at night or turn on air pumps, nothing bad has happened yet, i dont know about the others
