Squire's 90 Gallon Build, Now With Salt Water

[ensquire]

I know its only tap water, I know its crappy Iphone pics,
BUT IT IS WET... YEAH





So far there are no leaks and with everything running wide open there is good flow, I haven't had to throttle anything back at all and it runs very quiet with the Quiet One 4000. I haven't even tried the new pump on it.

The only issue I am having right now is that I am having a problem breaking the siphon on the return line when I shut the power off. As you can see by the following picture, I teed off and used dual loclines with wide mouth flows.
The top one is out of the water as soon as the pump is shut off. I think the problem is that the actual return line sits so low in the overflow. What do you people think? I could get rid of the dual locline and go with a single, but i was hoping to have that flow down low on the backside of the rocks.



I could just scrub the return line through the overflow and drill another return hole up high in the back and use the second hole in the overflow for a Herbie.

Just trying to get some ideas.
