New cloudy with addition of dry acid

[Poolray]

What did I mess up? Pool has been crystalline beautiful up til 2 days ago when I measured pH and found it was a bit high at 8.0. I mixed a pound of dry acid with 3 gallons of water and slowly poured half in the skimmer and the other half in the deep end.

A few minutes later my wife goes "What the heck is that?" A big blue cumulus "cloud" formed in the deep end of the pool. It eventually disbursed but now the water is no longer perfectly clear like it was, but the pH is right around 7.6 now. What to do? Will it just clear up in a few more days?

FC = 2
CC = 0
TA = 110
pH = 7.6
CYA = 40

I'm not sure, but your FC is too low for your CYA Pool School - Chlorine / CYA Chart

Yup, I just gave the pool a half gallon dose and bumped up the Stenner by a few minutes to increase the FC.

Water clarity is back to normal. All I can surmise is that there was dissolved stuff in the water that came out of suspension with the pH change. I noticed the filter pressure also went up enough to require a backwash, so the filter was catching whatever it was. I guess this means my water is even cleaner now, but it was a strange thing.
