Hi all,
After reading @Leah95 post earlier, it was discussed in there about the importance of surface agitation and gas exchange, and a very helpful video posted to view. This has lead me to some late night reading/watching on the subject and I am very new to c02 injection so this is all a steep learning curve. Therefore, it lead me to the video below, and also a couple of articles that suggested that simple agitation from a canister filter is most probably not enough when c02 off, lights out and plants have stopped photo synthesis. It suggested the c02 20-40ppm average, but also Oxygen 7-10ppm. Firstly, how can anyone test that? My understanding is that the equipment is very expensive.
I dont seem to see many people doing this, and I guess its why I am making this thread. Is there any benefit to running an oxygen diffuser/airstone in reverse of the lights/c02. Its seems quite logical but there must be reasons why it not favoured by many. Surely its not just aesthetics and people dont want to see yet another piece of equipment and pipe in the tank. I have looked in the archives and there are some very advanced conversations about dissolved oxygen, but the reading goes way above my head and leaves me even more confused than before I started. Ive put one of the videos below, and would appreciate your thoughts.
