Safe to swim?

[alben]

I had a sudden algae problem occur on the bottom of my pool. I was at the minimum FC level for a couple of weeks, and that must have been low enough for algae to start.

My initial readings a before shocking were:
FC 3
CC 0.5
TC 3.5
pH 7.8
T/A 100
CH 70
CYA 40
Temp 87F

So I high shocked to the following a couple of days ago:
FC 23
CC 0.5
TC 23.5
pH 8.2
Temp 83F

Today here is my current readings:
FC19.5
CC 0.5
TC 20
pH 8.2
Temp 83F

I realize the pH is high. The pH was 7.8 before shocking. Are pH readings not accurate at shock level?
My biggest question, is I have the iPhone pool calculator which for my chem readings, says
FC Normal 3 to 7
FC Shock 15
FC High Shock 24

Is it safe to swim at a FC of 19? I have searched the board, and it is general consensus that it is OK to swim at "Shock" level. Does that mean the regular shock level, or the High Shock level?

I have assumed it to be regular shock level. You may want to wait one more day to swim. High FC will raise pH temporarily.

I would wait until it is below "normal" shock level myself. It's not clearly posted which level you need to be below, but I'd rather be safe... esp if there are other people and kids involved.
