What is considered " optimal" ?
In the context of the statement where I used that word above, I was talking about O2 concentration and pH (CO2 concentration).
There may be different optima for different organisms, but I'd be surprised if less than 100% O2 saturation leads to more optimal health than does 100%.
I'd also be surprised if pH below 8.0 is optimal for any calcifying organism.
If you think otherwise, and prefer low O2 or low pH, then perhaps more aeration is not useful for your purposes.
