Thanks Marc, but thats fine. I will try it on a closed loop. If not, it will be a spare or perhaps sell it.

Now that my 3MD is running again, its actually quieter than before. :confused:

The pumps dont bother my wife or myself or the dogs, :D , Its only if we have excess company staying in the rec room. I have set it all up to be flexable. Of course the closed loop can be shut off if its bothering someone and I have a 800 PH also plumbed from the sump to the tank. If I have guests in the rec room, I can shut one or both Little Giants down over night. :D

Going to fire the closed loop up tomm.
