this is very basic and if i can i will draw one alittle better in sketchup
2 down arrows are inlets
#2: return pump section ( this is where you will see your evaporation and need to top off with fresh RO/DI water )
#3: refugium section
#4: external return pump
black lines are dividers/bubble traps. the single line on the right can be a bubble trap if you wish, personally thats how i did it with 2 bubble traps before the retrun pump.
the return pump section is drilled and fitted with proper bulkhead and then plumbed with PVC pipe to the right of the sump. the water then is pumped by the external pump back to the display shown by the red up arrow.
