When doing the alternating gyre are you using two A propeller or do you keep it stock A B....2 of the XF250's will run your tank easily. I dont know what people are talking about not having random flow. Yes if you leave them on constant the flow becomes a bit linear. If you alternate gyre them every 45 seconds the flow will be random.
