Aeration of water is a good thing.

Oxygenation, specifically.

There are thousands of articles about this all over
the internet (do a google search)
The link below is just one example.
Aeration of water , also helps eliminate
the oxides in rust.

Yes, that's true - but you're not going to get any significant aeration of
water in an air-over-water tank after the first few days. Since the tank is
not open to the atmosphere, the oxygen which reacts with various substances
in the water is not replaced. As soon as the oxygen is depleted from the air
inside the tank, any benefits of aeration disappear.
