Yes, granular pool shock should be dissolved in water before adding to prevent bleaching and ensure even distribution. Liquid shock can be added directly to the pool while walking around the perimeter.
You need chlorine for daily sanitation, but traditional pool shock products are optional. Liquid chlorine can serve both purposes and is often more effective than granular shock for treating pool problems.
Pool shocking involves adding liquid chlorine to raise free chlorine to shock level (based on your CYA), circulating for proper distribution, and maintaining that level until water clears. Always shock at dusk or night to prevent sun degradation.
You can typically swim 8-24 hours after shocking your pool, but the exact time depends on your chlorine levels returning to 1-4 ppm. Always test your water before swimming.
Pool shocking involves raising free chlorine to 10-12 times your CYA level to eliminate contaminants. Test water first, calculate dosage based on pool size and CYA, then add liquid chlorine in evening for best results.
Pool shock is needed when free chlorine drops below effective levels, after heavy use, storms, or when algae appears. Use liquid chlorine for best results and shock to proper levels based on your CYA.
Pool shock works by rapidly raising chlorine levels to oxidize organic contaminants like sweat, sunscreen, and algae. It breaks down chloramines (combined chlorine) and restores free chlorine sanitization power.
