The right moments

  • Right when you remove the winter cover (March–May in Houston).
  • Whenever your pool's been sitting un-circulated for 2+ weeks.
  • After a major water-fill or partial drain.
What to expect

Timeline

Swim-ready in 3–5 days · re-test water at the 24-hour mark.

Why we recommend this kit

After winter, your pool needs a shock to clear off-season buildup, a stabilizer top-up (CYA depletes over the cold months), alkalinity correction, and a season-long algaecide. This kit covers all four, dosed for your pool size.
