How do you determine how high to run your sump?
I've never done this, but I think I have an understanding of how it works. Tell me if this is right or wrong.
I'd think that you just fill the tank up until it begins to overflow. Then fill the refugium and skimmer compartments, Fill the return section up to 6" deep. Have 5g or 10g of water on hand to top it off and account for piping and pump volume. Turn it on.
Now you let it run and assure that all is overflowing and pumping correctly.
Now fill or drain the return section until it's the depth you want and then mark it with tape or a marker.
Kill power a few times and be certain it will not overflow.
