What Size Should My Overflow Be?
I'm getting ready to switch my freshwater tank to saltwater over then next few months, and I'm now finalizing plans and starting to work on all the logistics and such.
I'll be setting up a sump with a drilled gravity overflow, but I'm not sure what size pipes I'll need to keep up with my return pump. I'm not exactly sure on the pump yet, so if anyone could point me in the direction of a general resource that gives a range of figures for various flow rates, that would be great.
If not, let's say I have a 530gph pump with a static head height of about 38 inches. What should be the diameter of the overflow drain pipes te ensure that they can keep up? Thanks!
