Acceptable Sump/Display tank turn over... ?????HELP?????

[Bloodasp]

As far as I know if you have a refugium in your sump you need to slow down the waterflow into it so that the stuff you have in there could do their job efficiently. The rest to me is just trial and error up to this point. Just as long as the water is quite clean, there is minimal noise, and the water does not end up on my floor.
