I was at John Newby's Saturday and we were talking about tank return flow rates. I told him I had mine going as fast as the overflow would allow without flooding the tank. He told me that I should have it open just enough to have some flow out of the return but nothing fast. He said this allows the sump to draw more nutrients out of the water.
I just wanted to know what GPH others have on their return to the tank. I had mine at around 500GPH mainly so I could use the return as more current flow. I have a 55g tank just for reference.
I have seen many people use the Mag 5 and 7 for thier return but if that fast of flow is not wanted or needed then why have those big pumps on? I have a Rio 2100+ that puts out ~500 GPH at 4' head.
John showed me his return on his 135g and it was hardly any flow at all. Just curious what others had to say.
