Swimming pools blog

Hi everyone,
I’ve been seeing several different programs for maintaining pools
available on the internet. Pool Professor is one that comes to mind.
Have any of you tried these programs? They basically mimic what the
pool store does ….. you enter all your pool data like size and type
of surface, average operating temp, type of sanitizer, etc. and then
you enter your test readings and the program gives you the correct
amount of chemicals to add to achieve balance.
Just wondering if anyone had tried anything like this and how it worked
out?
