Above is something beside choosing the energy efficient pumps.
Looks like this is too ideal that I don't see anyone switching internal/external pump with season.

yeah probably leaning towards internal here as the added heat will be a bonus as this is in basement so save the heaters from kicking on. Also LED's planned for lights so not much heat added to tank.
