disbjohn, yes I have my skimmer in the 1st section, then baffels, then my return section.
Roger, it would indeed top off when the switch would get activated when I got a low level in my return section. I was just lthinking that there might be that loss of water going to the sump for awhile due to the wave action.......thus causing my auto-top off pump that is hooked up to the float switch on the return section to cycle on and off more than normal.
