Would a strong current at the surface cause aeration or does the surface of the water actually have to break?
I'm asking because I have my Fluval 405 outlet under the surface so that it creates a strong current, but no actual breaking of the surface (so that it's quiet). I have 3 air stones setup throughout the tank for aesthetics, but I might end up removing 1 or 2 if I rearrange and I don't want to do it if it lowers the oxygen level (if this is the main source of aeration).
The tank is empty while cycling, but I don't want to suffocate the fish once I do start stocking!
