Overflow with Sump for planted tank.
Hi everyone, i am new to all this and i would like to know if anyone has any experience with a overflow and sump on a planted tank? i have a 55 gal that i'm changing to plants. i plan on having angel fish in this tank. i am aware that i need to keep splashing down as much as possible. i am going to build my own sump to try to acomplish this. what i need to know is how much flow (gph) do i need to have on my return pump? thanks to anyone that can help me. this is a great forum!!!
