Let's not add anything to raise pH or TA for a while. I'd like to see it come down. Half a box of Borax would have had about half the effect on pH and little effect on TA. Right now (your cloud proved it) your pool is dangerously close to precipitating calcium either as a cloud in the pool or onto your heater or as scale at the waterline.

The CYA test is hard to read, I'd call 140ppm the same as 150ppm.

Keep the FC at 15ppm with bleach, if it drops below 10, check pH. Enjoy the party if you can - pool parties at my house are pretty stressful for me - I count heads alot. I really only relax when the pool gate is locked.
