How to fix low chlorine in CircuPool Core Water Filtration Systems?
- B
  Brandon LangAug 18, 2025
  If your CircuPool Water Filtration System shows a 'Low or no chlorine residual' problem, it could be due to several reasons. You might need to increase the output level, especially as temperatures rise. Also, increase the run time to at least 1 hour per 10° of ambient temperature, ensuring 1.5-2x filter turnover. For heavy pool use or bad weather, activate Super CL mode or chemically shock the pool. Check for water chemistry issues like low chlorine stabilizer or salt, or phosphates/nitrates; consult a pool professional to ensure chemicals are in range. Inspect and clean the cell if it's dirty or clogged. Verify sufficient water flow by inspecting the flow switch. Finally, ensure the system is turned on; if not, refer to the “No Power” section.

- N
  Nathan JonesAug 21, 2025
  If the Clean Cell LED is illuminated on your CircuPool Water Filtration System, it indicates that the cell requires cleaning. Also, verify the salinity. If the problem persists even after cleaning, the cell may need to be replaced due to reduced efficiency.

How to troubleshoot the 'No Flow' LED on CircuPool Water Filtration Systems?

  christophermartinAug 23, 2025
  If the No Flow LED is on in your CircuPool Water Filtration System, it means there's insufficient water flow or air bubbles. Check the water level, look for pump cavitation, and inspect for air or blockages in the plumbing, valves, and seals. Clean the filters and strainers. Additionally, check for any obstructions or buildup around the flow switch paddle, and dismantle the cell to remove any debris to ensure the flow switch paddle moves freely.

How to prevent mineral buildup on CircuPool Water Filtration Systems cell?
- T
  twhiteAug 30, 2025
  If your CircuPool Water Filtration System's cell frequently has mineral buildup, it's due to imbalanced water chemistry. Ensure that your Saturation Index is at or near zero.

Why does my CircuPool Core cell never have mineral buildup?
- M
  Mrs. Brittany HarrisSep 1, 2025
  If your CircuPool Water Filtration System's cell never or rarely has mineral buildup, the water may be corrosive due to imbalanced water chemistry. Ensure that your Saturation Index is at or near zero.

Why doesn't the chlorine output reach 100% on CircuPool Core Water Filtration Systems?
- A
  Amanda MunozSep 6, 2025
  If the Chlorine Output level on your CircuPool Water Filtration System does not reach 100%, it may be because the cell is dirty or clogged; clean the cell. It could also be due to a damaged cell or cell cable; in this case, contact Customer Support.

What does it mean when the 'Cell Life Low' LED is on in CircuPool Water Filtration Systems?
- G
  Gregory OrtizSep 8, 2025
  If the Cell Life Low LED is on for your CircuPool Water Filtration System, and salinity is within range, the system has likely reached the end of its lifespan. The cell must be replaced once the “Cell Life Low” LED is on and the Chlorine Output setting won’t reach 100%.
