ShelleyAnn,

I am confused by your post and this earlier one:
I finally won. It took tons of bleach also. I was starting to think the way it was smelling was normal, and that I was crazy to think there was something wrong. Well, now on the other side of it, I know that a healthy pool does not smell like chloramines. I just can't believe how hard it was to fight something that wasn't green or cloudy! It would have probably been worse if I didn't respond to the smell. I think brushing and vacuuming was an important factor to finally clearing it up.
What has changed?

I notice your Cl losses are during the day....not at night. Test in the evening and again the next morning....that'll tell you how much you're losing to the Sun.

Yes, I believe your altitude may well have an affect on Cl loss. The UV rays are certainly stronger at higher altitudes.

However, it's still not clear to me why you're not swimming....sorry to be so dense.
