You can paint the pvc black with krylon. There is not much of the outflow elbow that sticks throught the filter wall into the aquarium. I used the flexible tube because I was kinda in a rush to set it up. I am sure you could run an elbow straight down, the hard part would be securing it to the outflow so it doesn't pop off under pressure. Some threaded fittings that size would be nice.
