Hello, I have a 55 gal tank( long standard size) and I'm planning on having a sump under my DT. My problem is that I don't know how much flow I need for my return pump. Some people said around 550-850 gph and some others would recommend using at least 1000+ gph.
I'm planning on a reef tank and DIY pvc overflow if that helps.
