Ok, here it goes. 50 gallon tank, overflow box to a 10 gallon aquarium. Do I need to have some sort of union to adjust the amount of water going into the sump? Coming out of the sump? How should I set up dividers and such in the 10gallon tank? Im wanting to run my skimmer, heater and have some macro algae in the sump...do I need to put in anything else? Recommend return pump?
Im sorry, but Ive been searching, and Im just not getting the answers I was hoping. Pics would be great. I really dont know what Im doing here and definately dont want to make any mistakes.
If there is anything else I need to know, please tell me. I know I will need a light for the plants...I guess I can just plumb some pvc up for my return?
Have I asked enough questions? Should I ask some more?

Thanks again in advance.
