Is Seeding And Cloning A Tank The Same Thing?

Smaller angels do better with less current. I've found larger ones don't mind the current as much. As far as the blue hande I couldn't tell you, this might help; http/www.marineland.com/products/consume...nfiltersnew.asp

According to that site it says its called a mid level intake which increases the water flow in the tank. So should I close it so it won't bother the angels or should I wait and see?
