Solutions:

Please note that I-PURE uses a clear cell design. While the pump is running and the I-PURE is producing chlorine, you can verify the chlorine production by observing the water through the clear cell. The water should have small bubbles and have a hazy appearance as shown in the video. If a salt chlorinator cell is confirmed to be producing chlorine, but the pool's chlorine levels remain low, several factors could be at play. Here are the usual suspects:

1. High Chlorine Demand:
• Organic Contaminants: Heavy bather load, debris (leaves, pollen), or algae growth can consume chlorine faster than the cell produces it.
• Environmental Factors: High temperatures, intense sunlight (UV), or rain can degrade chlorine or increase demand.
• Solution: Test for combined chlorine (chloramines) and shock the pool with a non-chlorine oxidizer or liquid chlorine to eliminate organic matter.


2. Improper Water Chemistry:
• Low Cyanuric Acid (Stabilizer): Cyanuric acid protects chlorine from UV degradation. Levels below 30 ppm (ideal: 30–50 ppm for salt pools) cause rapid chlorine loss.
• High Phosphates: Phosphates (from fertilizers, cosmetics, or detergents) feed algae, consuming chlorine. Levels above 100 ppb can be problematic.
• pH Imbalance: High pH (above 7.8) reduces chlorine’s effectiveness. Ideal pH is 7.4–7.6.
• Solution: Test and adjust cyanuric acid, pH, and alkalinity. Use a phosphate remover if needed.


3. Insufficient Cell Output or Runtime:
• Undersized System: The chlorinator may be too small for the pool’s volume or demand.
• Short Pump Runtime: If the pump runs less than 8–12 hours daily, chlorine production may not keep up.
• Low Salt Levels: Salt below the recommended range (aim for 3,500–4,000 ppm) reduces cell efficiency.
• Solution: Verify salt levels, increase pump runtime, or adjust chlorinator output. Check if the system is rated for your pool size.


4. Cell Maintenance Issues:
• Scaling or Deposits: Calcium buildup on the cell plates can reduce efficiency, even if it’s producing some chlorine.
• Worn Cell: An aging cell (typically 3–5 years lifespan) may not produce enough chlorine.
• Solution: Inspect and clean the cell with a mild acid solution (per manufacturer guidelines). Replace if nearing end of life.


5. Testing Errors:
• Faulty Test Kits: Expired reagents or inaccurate test strips can give false low chlorine readings.
• Interference: High salt or other chemicals can skew some test methods.

• Solution: Use a fresh, high-quality test kit or have water tested at a pool store.



6. Algae or Hidden Contamination:
• Early Algae Growth: Invisible or early-stage algae can consume chlorine rapidly.
• Biofilm: Bacteria in plumbing or skimmers can deplete chlorine.
• Solution: Brush and vacuum the pool thoroughly, shock it, and consider an algaecide.

Next Steps:

• Test water for pH, cyanuric acid, phosphates, and salt levels. Salt Chlorine Generator operation raises the pH level of the pool.
• Inspect and clean the cell.
• Shock the pool to address organic demand.
• Ensure adequate pump runtime and verify the chlorinator’s capacity.
