The sump is another Jack and Jason project. It had to be built inside the stand in order to accommodate the size I wanted. So Jack got high on Weldon40
You know I don't even know the exact dimensions but I do know we were limited to hight so its about 25" high.
It is in the sump. As part of the sump design the center compartment isn't effected by evaporation so this will not reduce the sumps performance.
