Hello everyone,
I've been reading that the way oxygen(O2) enters my tank is through surface agitation (contrary to popular belief of air bubbles through air stones).
This is certainly something I want, to provide my fish with enough oxygen.
I have also read that a good source for my plants is to have CO2, but to prevent CO2 from escaping I need to reduce surface agitation.
Is it possible to achieve an equilibrium where I can have CO2 on the tank but allow O2 to enter? (I have an HOB filter)
As a side note, I have also read that it is important to stop CO2 at night (when there is no light source for photosynthesis), this because without lights, plants can't process CO2 and thus start consuming O2, competing with fish for O2 and eventually leading fish to suffocate due to lack of O2 and excessive CO2.
How accurate is this?
Thank you everyone.
