Ok stop, its cloudy? You're getting into a pH imbalance if its cloudy. The cloudiness is calcium carbonate in suspension in the water. There are many causes for this in a saltwater tank, most of which we cannot test for, but the symptoms are the result of a low pH. Regardless the action you should take is to stop adding chemicals, increase surface agitation with powerheads and if possible add an airstone. You might be having a bacterial bloom going on that is consuming O2 and depositing CO2 in the water, thus dropping the pH and causing calcium carbonate precipitation (cloudiness). Sit back, relax and wait for it to get better.
