Ok now that I have the sump that I am going to use I have been thinking about how I am going to put all of the plumbing together. I have come up with the following sketch.
I plan on using a 10 gal
tank for a refugium adn then a 30 gal
tank for a sump. have both tanks drilled have water flow into the refugium from a Y in the plumging of the return pump. Put a valve in the section going to the refugium to slow the flow rate.
Well here it is.
The dashed lines represent the water level.
