Looks like you overshot a bit with the CYA... Did you use liquid stabilizer? Also you need to lower the pH again...
We rarely recommend algaecide, and never copper algaecide. I am surprised you used it after just completing an ascorbic acid treatment... In any case, if you get your FC up and KEEP it up, you will clear your water.
Keep vac'ing the junk off the bottom.
If your CYA is indeed 100, you need to get your FC up to 25 and keep it there until
a) you can hold that level overnight
b) you have 0 cc's
c) your water is sparkling
