Just curious where others with bowfronts have placed their powerheads for the best flow patterns. I have three Koralia 3s, and a 4th if needed. Right now I have one on each side about half way up pointed directly at each other. The guy who originally had this tank had them set up that way, but the flow isn't that great around the whole tank. The third one is pointed up to agitate the surface. I'm open to any advice, especially anyone using a bowfront. Thanks in advance!
