5 Steps to Properly Chlorinate Your Pool
Test your water first Use a drop-based test kit, not strips, to get your current free chlorine level. Guessing leads to algae or damaged hair.
Know your pool’s exact volume Measure length × width × average depth × 7.5 for irregular shapes. Round down to avoid overdosing.
Use an online pool calculator Enter your pool volume, current chlorine level, and target level. Bookmark Trouble Free Pool or Orenda’s calculator.
Add liquid chlorine correctly Pour slowly near a return jet, not all in one spot. Never mix with other chemicals, especially acid.
Underdose and retest if unsure It is better to add too little and test again than to overshoot. Digital calculators are free and more accurate than guessing.
