Recently set up a new system, and from the sump i have 1.5" PVC reduced to 3/4" hose just before entering the tank. The 3/4" hose connects to the 3/4" PVC thru the bulkhead, and the at the top of the overflow each 3/4" return is split with 2 3/4" sections of loc-line. (Its the Megaflow kit that comes with Oceanic Tanks). My question is, why am I getting an abundance of bubbles coming out of just one out of the four loc line returns? If it was an issue of bubbles in my sump, I would think they would be coming through all 4. Anyone run into anything similar?
why is 1 return spitting out microbubbles???

Check all the fittings above the water in your overflows, you have an opening somewhere that is siphoning air into your return flow. also make sure your siphon break is clear and water is coming out of it. A lot of times I have found just exercising the loc-line around seals it up and stops the bubbles, thats the thing in my tank that does it a lot.
