There are two lines to sump but one is just a tube in the water. No flow. And yes the water coming from the tank is a straight pvc pipe...crazy turbulence even though it's completely submerged.

I hope you guys can see this ok....the water coming in is just a straight PVC pipe and it's creating tons of air bubbles, which are making their way across to my pump and getting shot right back up to the display tank.
The 2nd black tube is the one I mentioned is just sitting in the sump. That's an overflow line?
I actually just took off the filter sock but while it was on I had as many bubbles. I'll try a different kind maybe. I'll definitely switch to a tubing though, thanks to everyone for that tip. My LFS guy is supposed to come one more time to check out all my equipment, hook up skimmer, adjust lights etc...he said to just leave it down during cycling. I need to head to shop tomorrow anyway for few things so I'll see if he can bring tubing. If not I'll hit Home Depot.
What about adding elbows....still a good idea with my sump setup?
