Trying to figure out what to do in my new tank and how much flow I should be shooting for. The tank is a 200g 84" long and only has one overflow that will flow roughtly 1200gph. Should I have the other end drilled and install another overflow? I"m not real worried about moving more water because I will have a closed loop pump but am worried that all the dirt/junk can only get to my sump by way of one overflow in the corner of a 84" tank.
I"m still trying to decide between a couple smaller circulation pump, one large one, 1-2 tunze powerheads.....not real sure yet
, but I guess I should be looking for 4,000++gph
