  1. Calculate the volume of water in the pool using our handy pool water calculator.
  2. Take a cyanuric acid reading using your test kit or test strips. If the reading is below 30mg/l (ppm), you will need to add Fi-Clor Chlorine Stabiliser as below.
  3. The Chlorine Stabiliser can take a few days to dissolve. During this period assist dissolution by sweeping any accumulated product with a pool brush, keeping filters running. Do not backwash.

NOTE - For liner swimming pools, please refer to the liner manufactures operating guidelines.

Warning: Do not use together with other products. May release dangerous gases (chlorine).

Precautions: Never mix chemicals, except by dosing into the pool separately and at different times. Never add chemicals to the water when bathers are in the pool. Store in a cool, dry, well ventilated, secure place away from oxidising and reducing agents, eg, petrol, oil, solvents and organic materials; ammonia, fertiliser and nitrogen compounds; strong acids and alkalis. Avoid direct contact with pool chemicals. Should there be skin contact with chemicals, wash thoroughly.
