    You might just have to run the CO2 slightly higher to get to a good pH drop. Maintaining good gas exchange is more important than minimizing CO2 use. Keeping good surface ripple is actually more effective for gas exchange than an airstone.

    It's not going to counteract the CO2 conc in your tank as such, it's possible to maintain optimum CO2 and high O2 at the same time; the two are not mutually exclusive.
    The stream of air bubbles hitting the surface may cause enough surface disturbance to degas your tank's CO2 at a faster rate than a gentle surface ripple, created by a lily pipe for instance.
    I'd aim for a gentle ripple like @Christophe mentioned above. But using an airstone at night is a good idea If you want to increase gas exchange when plants aren't producing O2.
