pH/Alkalinity adjustment before SLAMMING?

[VA_Pool]

I just got my TF-100 test kit today. Below are the results. I have green/brown algae and plan on slamming the pool with bleach (8.25% Clorox).

FC = 0
pH = 8.2+ (more red than top reading on chart)
Alkalinity = 50
Calcium Hardness = 50
CYA = 0
Salt = 2400

I have read all of the shock/slam info on this forum and based on these results I assume I should lower pH level first? What would be the best way to do this and should I worry about the low Alkalinity level or pH first?

I am trying to figure out the most effective order and plan of attack since all of my readings are obviously out of whack... and what to add before using the bleach.

PH first. Lower it before slamming. Add muriatic acid per your gallons and pool math. You can fix TA after the process. I'd be tempted to raise cya to at least 20 and slam at that level.

I would also get my CYA level to 20-30 ppm. It takes the harshness out of the chlorine and you'll get protection from burn off from the sun.
