Doheny's Super Pool Shock, 24 lb

Use 1 pound of Doheny's Super Pool Shock per 10,000 gallons of pool water for routine maintenance. For green pools or algae issues, a "double" or "triple" shock might be needed.

To safely use Doheny's Super Pool Shock, pre-dissolve the product in a clean bucket of water before slowly pouring it around the perimeter of your pool—preferably in the evening to minimize sunlight breakdown. Always handle with care, wear protective gear, and never mix with other shock or pool chemicals. Follow all instructions on the Doheny's label for safe and effective application. Remember - always add chemicals to water, not water to chemicals!

The waiting time depends on the type of shock used and the dosage. For standard chlorine shock, it's generally recommended to wait until the free chlorine level drops below 3 ppm, which can take anywhere from 4 to 24 hours. Always test your water before swimming. Shocking your pool at night is ideal so your pool is swim-ready in the morning!

As a general rule, most pools benefit from shocking once a week, especially with regular use, high temperatures, or after heavy rain. You should also shock immediately if you notice cloudy water, algae growth, or strong chlorine odors (which indicate chloramines).

Common reasons include insufficient dosage for your pool size or problem, high cyanuric acid levels (chlorine stabilizer) that "lock up" the chlorine, very high pH, or severe algae blooms that require multiple treatments. Ensure your water is balanced before shocking for best results.
