I agree with Roger. Tunze 6300 designed for larger tank which required wide range flow. Tunze 6200 or 6100 should be able to handle your 360g. Tunze 6200 flow 3feets wide, i don't know your tank dimension but its should be able to cover all dead spot in your tank. When i heard about tuzne 6300, i really want to get a pair for my cube but again the 6200x2 is more than enough. I don't have any dead spot in my 48x48x24 tank.
