Plumbing question ?

[gregzz4]

Personal preference ...
I'd use the larger drain as the main

And ya, about the self-priming pump, good catch Cal

I'd recommend the heater be after the pump so it's pushing not pulling through it. Any air that gets into the heater may become trapped and cook it ... maybe never happen, but a thought

Will be dry plumbing the tank on Friday or Saturday but got to move it into the fish room first.

Hopefully things go well.

I may consider using a Durso for your main siphon drain. The reason is, you will have stagnance at the bottom of the overflow. Using a Durso will create flow in the bottom, and all you need to fo it place a siphon break at the top (assuming your sump cannot handle the volume of your overflow. Secondly, I would use the emergency as a trickle, since protein will build up on the surface of your overflow otherwise.
