I will be building my own sump within the next couple months for a 265gallon. From what the website says about the tank the returns can push up to 700gph each, so a total of 1400gph. The flow rate on the jebao dc-12000 is over 3k and at a head height of 5.5' it appears to be 1800-2000gph. So I'm assuming this will keep my flow maximized for what the tank can handle? I'm no expert in this stuff so I wanted to run it past some experts before I start ordering stuff. Thanks
