I just set up a Apex controller it is working great but I am having one problem. I have two Hydor Koralia 1 400gph pumps that I am trying to control, the Apex will turn them on however it will not turn them off, if I plug in a differnt pump into the same outlet without changing the settings the other pump starts and stops no problem. Are the Koralia 1's incompatable with the Apex controller?
