Powerheads just go wherever you want them, usually people will put 2, one on each side facing each other. Wherever there are dead spots or you feel there needs to be more flow, experiment and put it there. You can also point one towards the surface for surface agitation. It's okay, everything is new and we've all been at the place you've been. Looks like you have a specialty for FW though .
