Plumbing help with Megaflow overflow

I need to split the return flow. It's currently facing one end of the tank giving that end a high amount of water flow, while the other end not so much. All my fish hang out in one corner of the tank(the corner without the high water flow). I think by spliting the return flow in half, i'll be able to more equally distribute the water flow throughout the aquarium. So in order to do that, i need to split my Megaflow return nozzle in half. It's a 3/4 inch elbow that has a threaded 3/4 inch nozzle connected into it.

So according to the picture, I should buy an "F" and just snap that onto my "K" that i already have and then purchase another "G" so that i have two, one for each side of the Y connector. Will this work?

Should work I have one return pointing to the right back corner and one wrapped around the overflow and down towards the back left . Just so you know the one wrapping the overflow really isnt long enough to hit the far back corner (on the left). It creates a dead spot. Cyano loves it though...lol

I would be careful though. Most tubing like that is branded Loc-line. The stuff that came in my megaflo kit is not true loc-line. It would snap together but the fittings were not tight enough. I ended up buying all new pieces for mine. I believe there is true loc-line and a generic loc-line. When I ordered mine from FosteSmith, I thought I was getting generic but it was not.

I could be wrong but that was the experience I had.

so you bought an entire new plumbing kit? Did the Loc-Line stuff leak really bad to where it wasn't even effective or something because Loc-Line stuff is the only stuff i've ever found that would work i think. Otherwise i'd have to fabricate my own PVC spouts.

I initially bought a Y and a 6" of tubing with a spout. When I tried to connect the new pieces(Loc-line) with the stuff that came with the overflow kit, the joint was real loose and would not stay in position. I did not run water through it but it would have leaked.

I then went to a LFS and bought a new threaded piece and some more tubing with another spout. I am not using the locline style tubing that came with the overflo kit anymore.

I've been thinking about attempting to take my split return and making it a quadruple for better coverage... might be able to drop one of my powerheads out of the picture if so...

oppinions?

Well I just went ahead and did it last night..
I took the V off my corner overflow on the 90g tank.
I took a bunch of pvc pieces and extended the overflow pipe out about 1.5ft, with a T near the point of the original V and an elbow at the end.

Changed the main return pump from a mag7 to a mag12 to compensate for the extra head or whatever you call it..

Took two maxijet 1200s out, replaced it with a maxi 600 hidden behind a rock.

So far everything in the tank seems much happier with it this way...

This tank is a two sided tank, so the way the rock was layed out and the previous flow, fish tended to just ride in the current. Now the current isn't as swift in such a circular way, so the fish are all out and swimming and just simply more active.
