Just bought a nano skimmer for my 20g QT

Ok, honestly now, I bought it thinking it would help keep the surface from becoming dusty and maybe will help filter any serious ammonia bubbles.
If it doesn't work, it was only $15, and it does extend the filter inlet.
So I figured, what the hell, let's see how much pain I can cause myself as the tank level fluctuates
Guess I'm a sucker for testing junk
