Blue color tint after liquid shock - normal?

[MacGeng]

I had a CC of more than 0.5 so I decided to shock the pool using 2 gallons of Pool Essentials Chlorinating Liquid and turned off the salt generator. 48 hrs later the FC dropped back to 4.6. The salt gen is still at 0%. The pool water looks clear but now has a blue tint to it. Any idea why?

It’s really hard to tell here but I know that it’s not usually this blue/teal ish.

Maybe a metal like copper, but hard to tell for sure.

Most people are happy when their pool water looks blue.

Green, yellow or brown pool water is bad. Blue is good.

I want mine to be crystal clear.
