I just started building a new tank, its going to be a 75gallon with a 40gallon breeder as a sump. The tank will sit against a wall on an 18” side and will have the overflow drilled on this side. The tank will be viewable on 3 sides 2 48” sides and one 18” side. And back to my question, should I use an external return pump since I will have a free 16” of room under the stand or just stick with an internal?
I have always had a internal pump, what would some benefits of the external be?
