Welcome to our forum.
It is called turbidity and it is unusually caused by the total dissolved solids (TSD) being too high. It is a good sign to do a drain.Gary
It's like your water feels heavy when you're in your tub.And the first soak with fresh water, you'll wonder why you waited so long.Spahappy
Now wait a sec... There has to be some "cloudiness" when the bubbles are passing thru the water. That's just what happens. I suppose there could be an excess at some point though. Are you guys telling me that you have crystal clear water even when your jets are on?
