The pump and power supply is the same between both, the controller is the main difference. A nano osmolator that keeps pumping will have one of 3 issues. A magnetic interference issue (floats are magnetic switches and will be affected by magnets including the magnet holder if improperly installed), a siphon which will happen anytime the reservoir water level is above the end of the hose, most common if pumping to a sump and reservoir is taller than the sump, or a faulty controller but this is unusual and likely limited to a batch made in mid 2016.
