Pool Chlorine Problems: Complete Troubleshooting Guide
Expert solutions for all chlorine issues - from maintaining proper levels to solving complex chlorine problems in Dallas-Fort Worth pools.
Quick Answer
Common chlorine problems include low levels (add chlorine), high levels (wait or neutralize), rapid loss (check CYA and demand), and ineffectiveness (chlorine lock). Most issues stem from improper balance, high stabilizer, or contamination.
Safety Warning
- •Never mix different types of chlorine - explosion risk
- •High chlorine levels require pool closure until safe
- •Low chlorine creates dangerous swimming conditions
- •Always test before and after chlorine adjustments
Chlorine Problem Diagnosis
Chlorine Level Testing
Test free, combined, and total chlorine levels with DPD or FAS-DPD test
⚠️ Warning: Test strips are less accurate - use drop tests for precise readings
Identify Specific Problem
Determine if issue is too high, too low, rapid loss, or ineffectiveness
⚠️ Warning: Multiple chlorine problems often occur simultaneously
Check Stabilizer Levels
Test cyanuric acid (CYA) levels affecting chlorine effectiveness
⚠️ Warning: High CYA causes chlorine lock, low CYA allows UV destruction
Assess Chlorine Demand
Perform chlorine demand test to determine consumption rate
⚠️ Warning: High demand indicates organic contamination or algae presence
Water Balance Review
Check pH, alkalinity, and temperature affecting chlorine performance
⚠️ Warning: Improper pH significantly reduces chlorine effectiveness
Common Chlorine Problems & Solutions
Low Chlorine (Under 1 ppm)
Causes:
- • Insufficient chlorine addition
- • High bather load
- • Organic contamination
- • UV degradation (low CYA)
- • Equipment malfunction
Solutions:
- • Shock treat immediately
- • Add 1-3 ppm chlorine
- • Check/adjust CYA levels
- • Increase daily dosing
- • Service chlorinator
High Chlorine (Over 5 ppm)
Causes:
- • Over-chlorination
- • Chlorinator malfunction
- • Improper shocking
- • Calculation errors
- • Automatic feeder stuck
Solutions:
- • Stop adding chlorine
- • Allow natural dissipation
- • Use chlorine neutralizer
- • Increase UV exposure
- • Partial water replacement
Chlorine Loss/Demand
Causes:
- • Algae growth (hidden)
- • Organic load buildup
- • Low CYA (UV loss)
- • Phosphate presence
- • Biofilm in plumbing
Solutions:
- • Perform demand test
- • Shock to breakpoint
- • Add CYA if needed
- • Remove phosphates
- • Clean filter system
Chlorine Lock (Ineffective)
Causes:
- • CYA over 50 ppm
- • Poor chlorine/CYA ratio
- • Stabilizer buildup
- • Using only trichlor tabs
- • No water replacement
Solutions:
- • Partial drain/refill
- • Maintain 7.5% ratio
- • Use liquid chlorine
- • CYA reducer chemicals
- • Professional treatment
Chlorine Types & Uses
| Type | Available Chlorine | pH Effect | Best Use |
