If you weren't running the filter I can see it looking like that. I rand my filter not sure if it's right or wrong but if the nitrifying bacteria really is housed in your bio media inside your filter I think it makes sense that your filter should be on. I'm new to this hobby so I could be wrong.
You might be getting confused between fritz fishless fuel and fritz turbostart/fritzyme.
Fishless fuel is an ammonium chloride product, that essentially doses ammonia into the water so beneficial bacteria has something to eat during a fishless cycle. I think you did a fish in cycle so you wont have used this. There is nothing in there that should cloud the water if shaken up. It could cause cloudiness as a nutrient causing a bacterial bloom though.
Turbostart/fritzyme are both bacteria in a bottle (similar to tetra safestart). They are the same as each other, just different concentrations and can help speed up your cycle. This is more likely what you added during your fish in cycle. As this is live bacteria i can see it clouding up the water for a short time.
