Just wondered as I've never bothered with it myself?
+1 I also do aeration during the night to help remove scum on surface I did not try to raise the spraybar but I will definitely give it a go tooIMO night aeration is very important to combine in high tech setups very high levels of O2 with very high levels of CO2. By night I raise my spraybar and break the surface. This way I get rid of the scum, fish are happy and microbes much more. Co2 is needed in high and constant levels especially with high lights but we always forget that most of our tank critters are highly demanding organisms in terms of oxygen consumption.
I didn't pay attention to this but one month ago I started to aerate my tanks by night with strong rippling when I'm home and IMO tanks look much healthier (although I have not measured this progress properly of course, just my observation)

Yep, but I guess this way you solve only one of the problems (surface scum)... while aireation breaks the scum but also injects high levels of O2 in the water column (which I'm nearly sure will help the denitrifying bacteria to have more O2, to multiply and to break down more efficiently the dissolved organics thus will reduce the scum). Moreover your spend more electricity!run a surface skimmer over night to help with this!
