Return pump priming needed?

[Eb0la11]

Ya, sometimes I just want broader opinions and I know not everyone is reading my build thread. So more generic questions I sometimes post here. It all depends. I usually at least update in the build thread problems and solutions but sometimes the process is thought out in these separate threads.

The needle wheel is in my skimmer, yes. I have a separate pump that pumps water from my sump to my skimmer, through the needle wheel and then drains back into my sump. Its an out of sump model.
