I am finalizing my equipment list for an upcoming build. It will be a 180g tank with dual corner overflows. Currently, I have a Varios Controllable DC Pump (2700gph) on my supplies list. Am I fine using this and splitting the PVC to return water to both overflow corners, or do I need to get 2 separate, smaller pumps and run 1 to each overflow? I want to make sure I have the right stuff at the beginning, rather than trying to play catch-up while the tank is cycling. I was planning on just splitting the return line to both until I saw another user's build thread that had a separate pump for each overflow.
