Due to the inability to get the flow to direct up to the surface using my Koralia 3 power head, I chose to modify it. I found a thread on marine depot's website where some else said they did it, so I had to try.
What I did was take my exacto knives and cut out a notch in the base. I used two different blades as one is for gouging and the other for fine tuning the cuts.
When I started I think that I was only getting about a 45 deg angle from it. After I cut the notch I was able to get a 5 deg angle. Here are the shots that show the notch, angle before, angle after, and application.
