Aquarium Build Questions / Input

I have an airline in the top of mine. If I put my finger on it it will flush and fill over and over again. I think you need a bit more air going in there.
 
You don't really want it going straight down in the water. I use a 45 to angle it into the sump. If you have the overflow tube a few inches under the water it doesn't work very well because of all the air going down the drain.
