At what strength does hydrochloric acid fume. When I did some research, I noticed that the literature refered to 36% HCl and stronger as "fuming". What determines if the HCl will fume? Does it have to do with vapor pressure of the water and the HCl?

30% - 40% hydrochloric acid (HCL)is a volatile liquid, it's boiling point is 53C (127F), for that reason it form fumes at the normal room temperature.
10% HCL, is less volatile and emmits vapors same as water, it's boiling point is 100C (ca. 212F) .
Therefore any acid concentration above 10-20% will start fuming at abient temperatures.
The concentration of the acid determines when the acid solution will starts to fume.

It does seem that you had free chlorine in your pool but I'm not sure what caused it. If the bromine you add is in the form of sodium bromide than the bromine in the water is in the form of bromide ion. The chlorine in hydrochloric acid is also in the form of chloride ion so the two aren't likely to react. To get chlorine you have to have something that will oxidize it (supply the missing electrons.) But if your pool was testing for high levels of bromine then something else was oxidizing the bromide ion to make free bromine which is not as volatile as chlorine as will remain in solution longer. If that was the case then adding hydrochloric acid would supply chlorine ion which could react with free bromine Br₂ + 2Cl- --> 2Br- + Cl₂ So the HCl is lowering the free bromine level in your pool but at the cost of releasing dangerous levels of chlorine.

HCl gas is incredibly soluble in water, and water is incredibly soluble in HCl gas. Concentrated solutions of hydrochloric acid give off the gas by evaporation, and the gas then "collects" water molecules from moist air, and forms clouds.
