I added 4 pounds of stabilizer 6 days ago. My CYA reading is 50 (still shows gray dot). Will the gray dot totally disappear?

My FC is 1.5 today, PH is 7.5, alk is 80, CC is 0, TC is 1-2. Water temp is 78. 28'AG, 18,500 gal.

I also added 4 pounds of baking soda 6 days ago.

What would any of you recommend I do from here?

Once I get the right balance, I will be starting up my SWC. (Auto Pilot)
