Fi-Clor pH & Alkalinity Reducer pHred

Corrects high ph and high alkalinity. According to the method of
dosing, Fi-Clor pH & Alkalinity Reducer (Dry Acid) 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. More
importantly, it will reduce the effectiveness of chlorinebased
sanitisers as they produce less free active chlorine. High alkalinity
will make it difficult to adjust the pH as any correcting chemicals will
be taken up by the alkalinity and are unable to alter the pH.

Instructions

To correct pH

1. 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.
2. Pre-dissolve the Fi-Clor pH & Alkalinity Reducer in pool
   water using a suitable container. In order to avoid concentrated
   solutions, only dissolve a maximum of 500g of the product in 10 litres
   of water at a time, adding product to water, never water to product. If
   you need to use more than 500g Fi-Clor pH & Alkalinity Reducer,
   repeat the treatment. Dose no more than a total of 1kg at a time.
3. With the circulation system running, distribute evenly around the pool, avoiding the skimmers.
4. Continue filtration and re-test after 24 hours. If the pH is still high, repeat the dose.

To correct total alkalinity

1. Determine the total
   alkalinity level using a test kit or test strips. If the reading is
   above 200mg/l (ppm), pre-dissolve 1kg of the product as described, and
   pour the solution in a small area at the deep end of the pool. Each
   application will reduce the alkalinity by approx 10 – 20mg/l.
2. Re-test after 24 hours. If the total alkalinity is still high,
   repeat the dose until total alkalinity falls below 200mg/l (ppm),
   varying the location slightly but avoiding the skimmers.
