I notcied the TA went down, but the Ca went up.

I am going to add the bleach & MA right now.

FYI - The tri-chlor puck has NOT been in the pool.

Do you think I need to do the "keep it up to 15 for several days" thing again? Or just keep on with the normal Chlorine/pH adjustments?

You have to have a little patience when clearing up an algae bloom. If you shock the pool and don't keep it at shock level long enough to kill all the algae, then you're just wasting time and money. You need to shock it to 15 ppm and hold it there until 1) all the green is gone, 2) your combined chlorine is zero, AND 3) the water is clear. Only after all three indicators are met, should you let the chlorine come back down. And even then, you don't want it to ever get below 3 ppm. Letting it get below 3 ppm with a CYA of 50 is an invitation for the algae to come right back in. "The aeration thing" is not to clear the water up, but rather to raise your pH back up after you've added acid to lower TA. You can try turning the pump off overnight to let the stuff settle and then vacuum it to waste, or keep the filter running to try to filter out the dead algae, but only after you have killed all the algae and removed it from the water through vaccing or filtering will you have clear water.
