pH & Alkalinity Reducer

7kg, 25kg

Depending on the method of dosing, Fi-Clor pH & Alkalinity Reducer will lower either the pH or the total alkalinity in swimming pool water. High pH can result in cloudy water and contribute to scale formation and may reduce the effectiveness of chlorine based sanitisers. High alkalinity will make it difficult to lower the pH as any correcting chemicals will be taken up by the buffering action of the alkalinity.

  • Improves water quality
  • Fast acting
  • Corrects high pH & alkalinity
  • Ideal for all pools and compatible with all treatment products



Instructions - to Reduce pH

  1. Calculate the volume of water in the pool using our handy pool water calculator.
  2. Take a pH reading using your test kit or test strips. You will need to lower the pH if the reading is above 7.6.*
  3. Dose a maximum of 500g of Fi-Clor pH & Alkalinity Reducer in the pool water at any one time.
  4. With the filtration system running, distribute evenly around the pool, avoiding the skimmers.
  5. Continue filtration and re-test after 4 hours. If the pH is still high, repeat the dose.

Instructions - to Reduce Total Alkalinity

  1. Take a total alkalinity reading using a test kit or test strips. If the reading is above 150mg/l* (ppm), dose 1kg of the product in increments, in a small area at the deep end of the pool. This should be carried out with the filtration running and avoiding the skimmers. Each application will reduce the alkalinity by approx. 10 - 20mg/l (ppm).
  2. Re-test after 24 hours. If the total alkalinity is still high, repeat the dose until total alkalinity falls below 150mg/l* (ppm).

* 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.


Disposal When empty and providing it has been rinsed out on the pool. this container may be disposed of via household recycling.
