Welcome, Jnp!
If you're in learning mode, I hope you enjoy pool school as it will help you have a trouble free pool. I can't tell from your post how you're presently caring for your pool.
While we normally ask for someone to post test readings to assist in solving mysteries, there are generally two things that cause white, cloudy water at shock/slam levels...dead algae that turns white, or, as you mentioned, calcium combining with sequestered metals. In either case, since it clears, the temporary cloudiness not actually concerning in your case.
What might be concerning is that it does sound like you "shock" a lot, which suggests that you may not presently be following TFP pool care methods (forgive me if this is incorrect
If you were to consider following the TFP method of pool maintenance, I think you'd find you don't have to shock at all, and enjoy your pool with fewer headaches.
As you will learn in pool school, it starts with testing with a good test kit, then maintaining your sanitation with liquid chlorine to avoid high CYA (stabilizer) levels from pucks or dichlor. While some CYA is needed to protect chlorine from sunlight, pucks over time add too much, so eventually, users are always riding a nascent algae bloom and start a cycle of frequent shocking, since it takes more and more chlorine to work when the CYA is high.
So, if you're already TFP, its most likely that the cloudiness is just the effect of oxidization on the sequestered metals -- no worries...just observe your calcium levels for optimal range.
If you're not using TFP and are using bags of shock, (eg cal hypo, which will more readily combine with sequestered metals if you already have a high/saturated calcium level), then you might wish to consider learning about an approach that doesn't rely on constant or haphazard shocking here in pool school.
I'm on a well and have metals and am really grateful that I no longer have to shock/slam at all since learning TFP. It was more than worth the learning curve!
Best wishes for a trouble-free pool!
