Sump Pvc length for returns

[fishstix]

Setting up my new sump, how far into the sump from the sump bulkhead should the Pvc go into the water?

Thanks

Just enough to kill the noise and splashing. A couple of inches should do it.

I have mine just touching the water line. You can always extend it with couplings.
