Flow

[Damarferg]

Should I position my flow toward the surface for surface movement or let the flow go in the middle of the water

I point all of my powerheads towards the surface for more agitation of the water. Oxygen is never a bad thing.

Depends on how deep your tank is?

If its more than 2' than I would have one in each corner pointing up & the other down while on different sides of glass. Just so you don't have to much build up on the bottom.
