reverse sump?

[lockrookie]

if you can draw up what you are thinking and ppll can see if it will work i have a couple thoughts as to how i would do it if i had to. sort of speak

1) i would build n external overflow of sorts onto the back of the tank that was more of a return section for the return pump(so you dont see it in the tank then on the overhead sump have a pump identical to return pump returning water to the display or another overflow draining to the display most likely would have a baffle free sump tho but if a pump fails it could cause probs.

2) i would build an internal dummy wall to hide the pump to send to the sump and the rest same as above.

my biggest concern would be tank overflows from sump to display.as well as where you would see the evaporation in dt or in sump. but if you use two pumps it may work best make sure you have a ball valve to adjust flow tho to match

or i could be way off base its just what my thoughts where lastnight thinking about it
