So the pumps each handle a different side and only the one circulates while heating, so just one side moves water. Got it. Thanks!

No one?

I have a used hot tub I'm trying to get working correctly. Is it correct that my Marquis Euphoria, when on circulation/heat cycle, is only moving water through the pipes on one side of my hot tub? Both sides work when I turn on the pumps, and the blowers work. The right pump (160?) is pretty hot but sounds as though it is working. Also, it is my understanding that if the ozonator is working it will "glow". Should the glow be very obvious? I ask because I see no appreciable glow, in daylight at least, when in the ciruclate/heat cycle.
