Using this specific product

BioGuard Smart Shock is listed here as the Multi-purpose shock version for pool shock and swimming. For treating pool or spa water, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Multi-purpose shock; related versions can use different timing.
  • For pool shock and swimming, pay particular attention to pool volume, circulation, dosage and starting chemistry.
  • Use only as directed; the current package directions control.

How to check readiness

Test the actual water and meet every label limit before anyone enters. When the timer ends, test the water. Entry depends on measured chemistry and the label, not elapsed time alone.
