I have the exact same problem. Spa water clear and is clear when all the jets are opened up but as soon as I turn the air-jets on the water turns like MILK. When I initially change my spa water every few months, I turn on the air-jets and the only WHITE water is out of the jets (air introduced is why). But when I turn the air jets off then the water turns clear 15 to 30 seconds later. Now the MILKY WHITE water is again a problem when air-jets are turned on. Balances all fine. I use clorinated sanitizing granules. I have NO foam issues either. I just keep using the spa with air-jets OFF.
