Next time you do a water change test your tank water before doing the water change and then when you notice it cloudy test it again.

Tap water, both hot and cold, contains dissolved atmospheric gasses. But the ability of water to maintain those gasses in solution decreases as the temperature of the water increases. The hot water is still able to contain those gasses as long as the water is under pressure in your plumbing system. But as soon as it exits your faucet and the pressure suddenly drops to atmospheric pressure, the gasses are forced to precipitate. The happens so suddenly that extremely small bubbles are formed, almost too tiny for the naked eye to see. These are what give the water a cloudy appearance.
