Free checklist

The DFW month-by-month pool checklist

What it covers (12 months · 76 tasks · 12 marked critical):

  • Freeze nights (January and December): keep the pump running, and what to drain if the power goes out
  • The March opening: test everything, brush, shock, then balance alkalinity, pH and calcium
  • Summer: testing two or three times a week, the weekly shock, and what to do after rain or a party
  • Fall leaves, and easing the chemistry down for winter
