My Pool Looks Like An EASTER EGG!!! -- NOT a good thing!

[PopcornGirl]

Wow, I appreciate you guys so much! Thanks for all your help...

Ok, sorry about the typo last night (too tired after an exhausting day); yes, my CYA is 65.
***Aside: The Black Algaetrine was added about 3 weeks ago, two days after the initial vacuum & shock...
I'm *pretty sure* that it is black algae (black freckles and streaks in localized areas).
By the way, the black algae (or whatever it is) is STILL THERE. So, maybe you're right; maybe it's not...***

I will definitely do what you say... add muriatic acid (wait 3 hours), then add the bleach, but I'll wait until around 3 or 4 this afternoon when the sun is no longer on that side of my house so that I don't end up converting all of my chlorine!
I am confused now about whether or not to put the puck in the skimmer... it is definitely a tri-chlor puck and I certainly don't want what Waterbear suggests to happen! Interestingly, Waterbear, it was my pool store owner who first suggested putting a puck in my skimmer -- had me do that last week. Thank goodness, that's the ONLY ONE I've put in there so far!

Also, I have TWO bottles of Metal Out; should I just add the one?
And according to the REGAL manufacturer's instructions:

It is advisable to add this product at least one day prior to adding algaecide or chlorine.

So should I add the Metal Out NOW and do the acid/bleach TOMORROW???
Or if I do the Metal Out now, 9:15 am CDT on Monday, can I still do the acid/bleach tonight (say, around 7pm & 10pm, respectively?). Would that be enough of a window between the two?
I realize that y'all are having to do a lot of "hand-holding" with me, and I apologize, but I'm a fast learner and I want to learn, so don't give up on me!
Thanks again,
