Aerobic bacteria suck down oxygen like no tomorrow.
And, um, Aerobic means? .

Requiring oxygen
Went cruising google, my favorite activity when the dishes call and
found:
*Aerobic digestion of waste is the natural biological degradation and
purification process in which bacteria that thrive in oxygen-rich
environments break down and digest the waste.
During this oxidation process, pollutants are broken down into carbon
dioxide (CO2), water (H2O), nitrates, sulphates and biomass
(micro-organisms). By optimising the oxygen supply -with so-called
aerators- the process can be significantly accelerated*

So lots of oxygen in the water is a goooooooood thing, as Martha would
say.
