5 Steps to Shock Your Above-Ground Pool Correctly

Test and balance pH and alkalinity first Shock only works effectively when pH is between 7.2 and 7.4. Adding shock to unbalanced water wastes money and won’t clean the pool.

Shock at dusk, not in the morning Sunlight burns off chlorine quickly. Shocking at night gives the chemicals hours to work without UV interference.

Follow the label dosage for your pool size Guessing the amount leads to under- or over-shocking. Measure precisely based on your pool’s volume.

Broadcast shock around the edges with the pump running Pouring shock directly into the skimmer can damage the filter. Let the pump run for at least 8 hours after application.

Wait for cloudiness to clear, then wait 24 hours to swim Cloudy water that clears means the shock worked. Swimming too soon risks skin and eye irritation.
