Is it possible? Too much oxygen?

[Bushbaby11]

Ive been growing in Dwc on and off for a few years now and I've never really thought about it but can you actually have too much oxygen in the res? I usually have 2 air stones in each 20L bucket from a Charles austen linear air pump et30 but on this run ive decided to put 6 airstones in each res to see how much of a difference it really makes??

So my question is can i put too much oxygen in my res?

No, it Hits a limit where it doesn't matter how many you add. The bubbles aren't adding oxygen, it's the breaking of the surface that allows gaseous exchange.
But you're DEFINITELY adding more heat than you're DWC can handle with that much air. Remove all of them and just use waterfalls
