Bacteria

[Apehanger]

One of my other hobbies is winemaking. When yeast is first introduced to to my juice it undergoes aerobic fermentation. The idea is to get as much oxygen to the yeast as possible, to enable rapid growth.
I was wondering if I was to tee off my air line and fit a small airstone near the input of my filter, would this increase the efficiency of bacteria growth?
(I'm an ex-engineer, so my mind is always looking for alternative methods to improve things)

I don't think you're going to like the sound it will make. loll.

If you draw air in the filter, you will also risk unpriming the pump and that could lead to damages.

Beneficial bacteria benefits from air contact, but not your impeller... Most of the time people use bio-wheel to create very large colonies and are used with heavy bioloads.

Okay. It was just a thought. Thanks.

Now, a lightly fed airstone in the basket area of the filter might be interesting. I am not, however, an engineer. As well, an airstone out of the intake but not far away could pull oxygenated water...

Air in the outlet side is totally acceptable for some filter systems and built in on others. The fluval U series filters have valves to introduce air into the outflow. Below are the instructions from the U series.

As mentioned previously, air into the intake side will have issues.
