Koralia pump positioning help needed

[InfernoST]

Hi Guys
I currently have only 2 Koralia 3's in my 120 (60x26x18) and find it not to be enough flow so I ordered 2 Koralia 4's (Should be here tomorow) to add to the tank. Can someone help me out with the best way to position the 4 pumps within my tank.

Thanx

I would put the 2 K-3's on the back glass in the corners and point them towards the middle of the tank. The 2 K-4's can be on the sides and point towards each other.

Thanks Larry, when I get them I'll give that configuration a go.
