powerhead recommendation

[saleen385]

have a 180g mixed reef. the overflows are in the middle of the side panels. need a recommendation on power head size and possible placement.
was thinking of going with jebao pp20's or pp15's, one on each of the side panels.

thanks,
Jim

I just got a pp20 for my 180g and it moves a ton of water. I'm pretty happy about it.
