The long and short of this is that when I turn the spa on (heater running, pool off, no blower) the spa becomes incredibly cloudy. When in pool mode with the pump running (return water goes to the spa and pool) the spa water is crystal clear. It appears that the chemicals are balanced with the pool water when it is cloudy. Should I be concerned? Is this just the affect of micro water bubbles or something much worse. Attached are pics of the pool water. As you can see you can barely make out the main spa drain that is 3 feet deep, but the main drain in the pool that is 6 feet deep is crystal clear. When I go into pool mode the spa clears up and looks like the pool. Any thoughts?
