But so you don't think it's time to up the air pump quite yet?
If you mean up the LEDs... no, wait until there is more growth.

better to use a normal airstone with bigger bubbles?
Yes for scrubbers, bigger bubbles are better, because it create more air/water interface, which remove the boundary layer around the algae. also it creates larger openings for light to get in.
