Stopped at the pool store today to pickup more CYA stabilizer and thought I'd ask about liquid chlorine to see how much it is even though I've been using generic grocery store bleach so far to raise my FC. The pool store girl showed me a gallon of "Liquid Shock" which was labelled as 12.5% Sodium Hypochlorite and which cost $5. She then suggested that it would be more cost effective to get a 16 oz. bag of Turbo Shock for $5 since that had 78% chlorine in it:

Side note: I think the chemical it actually contains is Calcium Hypochlorite which I'm assuming is different. Also, not totally sure she is right about that being more cost effective since it seems like a different chemical and I was buying 128 oz. of liquid vs. 16 oz. of powder, but what do I know. I majored in English.
She also mentioned that I shouldn't use grocery store bleach in my pool water.
Me: Why not?
Girl: It has extra chemicals in it that can cloud your water.
Me: Like what?
Girl: I don't know. I just know that it does. This [the liquid chlorine] is made especially for pool water.
Me: Um, okay.
So, I got the liquid chlorine and now I'm wondering two things. First of all, pool store girl is off her rocker, right? Obviously, I'm not using lavender scented bleach so it's not actually gonna cloud my water. It's literally exactly the same chemical, correct? I mean, the liquid chlorine isn't made by magical pool fairies who sprinkle it with a special pool dust, right?
Also, maybe someone who is better at math can tell me the answer - which is the cheaper option?
121 oz of 8.25% sodium hypochlorite at $3 a bottle (labels says it yields 7.85% available chlorine if that matters)
OR
128 oz. of 12.5% sodium hypochlorite at $5 a bottle
Keep in mind that choosing the second answer as the more cost-effective option means seeing pool store girl and getting her helpful advice yet again (of course, it also means I will be spared the horror of cloudy water from my grocery store bleach).
