Newbie needs help. Need a Plan Of Attack To Get This Pool Open

[NullQwerty]

Ok...Things are going good. This morning I woke up and the pool 10X better. Still green, but a much lighter green and there was actually some blue. The filter actually ran 2-3 hours without needing a backwash.

I threw in another gallon of the Chlorine shock. I then opened up the filter and found a bunch of DE (around 1" thick) dispersed at the top of the filter fingers. So I cleaned that out and reattached. The pressure after restarting was around 10 which I haven't seen in quite a while.

I tried vacuuming, but that caused it to need a backwash within minutes.

So, I took a water sample to the pool store (about 2-3 hours after adding that last gallon of chlorine shock). My results were:
Saturation Index: -0.1
TDS: 600
Tot Chlorine: 1.5
Free Chlorine: 1.5
pH: 8.4
Demand Drops: 3
Total Alkalinity: 42
Adj. Total Alk.: 42
Total Hardness: 79

So, at the suggestion of the pool guy, I added 45 lbs of Alkalinity increaser and 2 bags of the granular Super Sockit chlorine shock. Then in 2 hours I will add 6 lbs of PH Minus. Then, in the evening I do 2 more bags of the granular Super Sockit chlorine shock. All while I still have the three 3" chlorine tablets floating around.

After adding what I've added so far, I brushed the floors as best I could. That must have stirred up some of the remaining algae because the pressure builds up within 1 hour again, but I'm assuming tomorrow it will last longer. If not, and the algae looks better, then I'll probably acid wash the filter.

If anyone thinks I should adjust any of that, let me know. Things are looking up though.
