Asked this in my journal but no response so figured I'd try here as well...

So with most el natural setups the general idea is to have as little surface movement as possible to hold in CO2 produced by decaying matter in the bottom of the tank. However, as my tank only has about 25cm of water in it, I wondered if it might be better to keep the surface rippling so as to maintain equilibrium with atmospheric CO2 levels?

Either way its not going to be much, but every little helps :lol:
