I do get the few hints of chlorine form my pool when it is in what I think is great shape. I have had to shock my pool twice this year so far and they were after 3 to 4 in rains because my combined chlorine went above 0.5 ppm. My pool sits under some large oak trees and bugs and other organics end up in the pool after big rains. If the pool looks good, combined chlorine less than 0.5 ppm, or you have a good reason I wouldn’t worry about shocking due to a few hints of chlorine smell.
I would think you would have greater chlorine loss due to uv at your altitude. If people have greater exposure to uv so will your pool.
I am not sure about out gassing being greater but it would depend on the chlorine being in a gaseous state. I know according to Henry’s Law if chlorine were in a gaseous state it would out gas at a higher rate in Denver than in Miami due to atmospheric pressure. I am not sure about the amount if chlorine present in the water in a gaseous form. I agree with Dave might be smelling out gassed chlorine as well.
I do have few questions. How much Borax are you dumping in? What is the ph when you get the chlorine smell?
You have a good ALK so you should not see too much swing in ph and the bleach should cause the ph to rise. I also wonder if the low ph may cause more of the chlorine in the water to reach a gaseous form.
