So, I have a few questions for you large tank owners. I want a 500-600g aquarium. The length of said tank would be roughly around LxWxH (144”x30”x30”). It would be custom ordered and I would want a large center overflow with 3 dump lines and 2 return lines.
My question, can you use two pumps to create more flow? An example is if I use 2 COR20 rated at 2000g each will I be getting 4000 if each pump was its own pump running from the same sump.
