This actually helps to distributes the mist better, since it spreads it out evenly.

I do the same thing for the sumps I use and feed the outflow from the CO2 reactors directly into the return lines.

You can use flexible clear tubing of anytype and hide it along the back wall, even bury it where appropriate and have little elbows pop up.

They also make those rotating powerhead flow divertors.
I use this with aeration for a marine tank.
