Should I be going by the Pool Math one or the newer one the Pool Calculator on my home computer?
I'm getting different amounts of how much chlorine to use to shock my pool .
The original Pool Math one says Shock is 29 and the newer one the Pool calculator says 21 form what my readings are now.
Just curious way they say different amounts.Was the newer one updated and should I just use it now?
I'm going to be buying the App for my smartphone when I get it.
Getting tired of running in the house to use the desktop every time I need to add something.
Thank you guys for all the help
