I'm wondering if I should change the placement of the powerheads in my 29 gallon biocube. The one that comes in the tank was upgraded- but I don't know to what! But that one is pointed straight and up on the surface. I have a koralia 240 directly across from that on the top left front corner that is going towards the opposite back right corner. In the back right corner I have a koralia 425 facing the direction of the 240. Is there a better configuration?
