Ok so I am building an overflow box and to help keep it going in case of power outage I am adding a power head. Now the question I have is this, in the readings on how to make it start the cifen process I believe I am supposed to connect the in flow of the powerhead to the cifen part of the overflow which would have the power head running dry, so do I do the oppisite and have the output of the power head pump into the overflow cifen? I am going off a couple designs and doing my own, but this is the closest to what it will look like: DIY Overflow
Thanks.
