hey everyone. i am planning on building and fiq out all the plumbing for my sump/refugium this week. i have made many designs but can not get around my pump choices. so to get things rolling i need to decide, external or submersible pump. i have two overflows and will be running two return pumps. one for sump with skimmer the other for refugium. one of the pumps will be going through my chiller before returning to the DT, the other straight to DT. i can design the sumps for either external or submersible pump or maybe go with a submersible for return only pump and external for chiller flow.
my thoughts;
external pros-less heat production, less power used almost 1/2 i think, can use pressurized pumps for chiller, easy to clean. thats about it.
submersible pros-more water volume in sump, less plumbing, less noise(not sure though how much less)
external cons-more plumbing of course, less water volume but more usable sump area(maybe), more noise(maybe)
submersible cons- heat production, more power consumption, more wear/tear from Ca percipitates and things, uses up space in the sump.
any other thoughts?
