side by side sump and display tank

[123and456]

I am wondering if this idea will work well or not. Here is the plan.

1. The two tanks are setup next to each other
2. Take 2 2-1/2" pvc in the form of a U that will have one end in one tank and one in the other. By filling the pipes with water I am creating an auto leveling between the tanks. (i think this is a water bridge or called something to that effect)
3. I am using a XP3 with the intake in one tank and the output in the other.

I think that this setup will be very simple and since I am using 2 pipes if one gets clogged by something I will not have a flood since I have the second pipe.

Additional flow will be provided in the display by PH's Tanks are 20L

In theory it should work just fine. You WILL have a flood if the siphone breaks for any reason.

There are several examples of this type of setup on the internet and here at RC.

askin for trouble! Just bulkhead them together for a fail safe combo.

I also feel that this is asking for trouble if you do not put some failsafes in place....

and yes I can spell siphon!
