How often should I test pool alkalinity, and should I adjust alkalinity or pH first?

The answer
What to know.
Check total alkalinity at least once a week during swim season. Test it any time your water chemistry changes significantly, too.
Always adjust total alkalinity first, before making major changes to pH. Keeping alkalinity stable makes pH easier to manage.
