Would i have TOO much flow??
 

I have a 46 gallon bowfront tank. Im thinking of getting two Seio 820's for it.

Would it be a good amount of flow? too much? not enough? Should i get the Seio 1100 instead? thanks for any input.

I have 2 820's in a 35, but they are running restricted flow and directed upwards toward the surface.

livestock?
 

what are you keeping? if you are keeping acroporas, then the flow is great. if you are keeping LPS/softies, that should be fine.I find the seio's flow very "weak". if its too strong, then aim the flow at the long pane of glass, the bottom (if its barebottom), or the water surface
