Welcome to our forum.
When adding chemicals to a tub (weekly shock, enzyme, chlorine, etc.), instructions usually say to add the chemicals and run the tub for 20 minutes with the lid open. Does it really matter, in terms of overall water quality? Sometimes I will toss in a scoop of chlorine just before rushing out the door to work in the morning, but not run the tub. I figure that the granulated chemicals will dissolve within a few minutes, and that since the circulator goes on and off several times during the day, the chlorine will eventually fully circulate throughout the system and do its thing. Thoughts?
I don't worry about leaving the lid being open...I believe that's only if you intend to use the tub shortly after adding chlorine which I never do. I add chlorine after a soak to sanitize, never when I'm going to be using it.
Actually the off gassing of the chlorine will degrade the cover faster. And the off gassing is heaviest right after adding.

If it degraded the cover it must have been by a small percentage...it always looked the same to me.
