diy reactor

i have a question as to why when making reactors for an inline deal for use with canister why the gas is injected at the top of the reactor?

gas is injected into the space so it has contact time with the water to diffuse. it seems like it works the same way as a skimmer, bubles have max contact with the water. but in a skimmer the air is injected at the bottom so as they rise they have contact. but in all the systems i see from yall the gas is injected at the top. does the gas diffuse that quickly? or there another reason not to inject the gas at the bottom.

The outflow would blow all the gas out of your reactor. At the top it gets tumbled around till its all gone.

Your method would work at some rates of flow, but fast flow would blow the CO2 out the reactor and into the tank. Injecting at the top works fine at all but the most extreme rates of flow.
