Water Flow is Redsea Nano 20gal

[r212019]

So I've recently purchased a Redsea Nano Reefer and I love the tank but I need some help. I current have a Jebao SW 2 nano power head in the back left corner face straight ahead. Is facing the powerhead straight the best placement for flow? Should I be adding a 2nd power head on the other side of the over flow as well? In a cube shaped tank, is it best for the water to rock back and forth or should it be swirling in more of a circle? any input how how to position the power head would be much appreciated. should the power face towards the middle, top or slightly down towards the sand? i have Bahama sand so any sort of flows would blow it all over the place.


i'm using a Eheim compactON 1000 for my return pump in the sump, is this strong enough?

im looking at having mostly lps, zoas and softies. I might bet a few sps down the road but thats not my main goal. I currently have a couple clowns and inverts. I'm running an AI Prime HD.
