Hi mate, welcome to ReefBase
Cloudiness likely to be bacterial bloom from the reef maturation kit, depending on which of the potions you added. One is a bunch of strains of bacteria, (Nitro Bac) & Nopox is basically bacteria fuel. You probably do not need to be adding this last one yet. I can't remember exactly what bactostart is, might want to check the instructions on that one.
My advice would be to slow down, don't change/add anything and check it again in a few days.
Keep the skimmer on as bacterial blooms can deplete the oxygen in the water and the bubbles will help aerate the water.
Also...What are you using to test salinity? And when/how was it calibrated?
Can you post a pic so we can see how cloudy it is?
