Best placement for two koralia 4's

[reefpeeper]

I have two koralia 4's in a 30g cube. What would be the best placement for them to get good flow over the bottom area of the tank. This is a bare bottom frag tank. All that is in there is eggcrate to place plugs in.

When I had my 55 I had 1 in each corner angled towards the middle of the front glass and had good flow. 2 K4's in a 30g should give you good flow wherever you put them though.
