Have you been dosing calcium at all. I have had this same problem early in my days, nd it was from dosing too much calcium and not testing for it.

All I did was leave it alone for about 2 weeks doing nothing but water top offs, and it cleared itself up.

Does it look like underwater smoke? If so, it might just be a microscopic bacterial bloom, you can do a water change or just let it pass on its own/

It's more than likely either calcium precipitation or a bacterial bloom, as others have stated.
