Surface Agitation/CO2 Levels/Oil Slick
What would you guys do? I have a powerhead in my tank that I attached to a CO2 reactor that diffuses the CO2 perfectly, only problem now is that I have no surface agitation. CO2 is always at optimal levels now since there is no agitation. Oil Slick now builds up because no agitation. I am trying to save power. I don't want to point the outflow of the reactor up because my CO2 is coming out of there.
Optimize CO2 vs Oil Slick
