How to fix insufficient sodium hypochlorite in Intex Krystal Clear ZS6110?

  Lisa AndersonAug 13, 2025
  If your Intex Water Filtration System isn't producing enough sodium hypochlorite, consider these possible causes and solutions: * Increase the daily operating time of the Ozone & Saltwater System if it's not running long enough. * Check the salt level with a test kit and adjust if it's below 2000 ppm. * Use a pool cover when the pool is not in use or when the unit is operating to prevent sodium hypochlorite loss due to sunlight. * Inspect and clean the electrolytic cell if it's clogged or dirty. * Cover the pool with a pool cover for 2 days with the device running and then test the water using the test strips if there is high UV level exposure. * If the pool is clean and clear, add stabilizer to the water and then test the water with the device running.

Why are there white flakes in my Intex Krystal Clear ZS6110 pool?
- Q
  qjohnsonAug 20, 2025
  White flakes in your pool water when using Intex Water Filtration Systems are usually due to excessive calcium hardness. To resolve this, drain about 20 to 25% of the pool water and add fresh water to reduce the calcium hardness. Also, inspect the electrolytic cell for scale buildup and clean it if necessary.

What to do if the Intex Water Filtration System LED panel code flashes and alarm is on?
- T
  Thomas BurnettNov 5, 2025
  If the LED panel code flashes and the alarm sounds on your Intex Water Filtration System, several issues could be the cause: * The filter pump may not be attached or switched on: Ensure the filter pump is properly attached and running. * The circulation line could be blocked: If your unit uses plunger valves, make sure they are open. Clear any debris or dirt from the filter cartridge and cell. Also, release any trapped air in the circulation line. * The inlet and outlet hoses might be incorrectly connected: Check the direction of the hoses and reverse them if necessary. * Scale might be present on the flow sensor: Clean the flow sensor, paying close attention to the hinge. * The flow sensor cord could be loose: Ensure the flow sensor is firmly plugged into its receptacle. * Th...
