Where does the evaporation occur if one is using a sump with overflow boxes?
The water level in the display tank remains constant, correct?  The water
level in the pump return chamber will see the evaporation?  I am using float
switch to regulate the kalk flow to the pump return chamber.  The sump was
based on Marc's design.
