CO2 danger (I've been thinking again)
I have a DIY yeast CO2 reactor on my planted 150. Until it begins producing CO2 I just hang the hose in the tank until it starts bubbling. It occurs to me that this CO2 rises to the surface and then, since it is heavier than air, it must sit on the surface of the water below the level of the tank rim. Is this a) effectively adding CO2 to my water, b) forming a carpet of death that suffocates my fish, or c) pretty much nothing at all?
