Blue Horizons Chlorine Reducer (1kg)

£9.35In stock

Blue Horizons Chlorine Reducer completely removes all chlorine or bromine in a swimming pool


Blue Horizons Chlorine Reducer is used to lower bromine or chlorine levels in pool water after shock treatment procedures or as a problem solver if the pool has been accidentally ‘overdosed’ with chlorine or bromine.


  1. Pre-dissolve the product in a clean plastic container at a maximum rate of 100g of product per 3.3 gallons (10 litres) of clean warm water. Stir well to ensure product is fully dissolved. Carefully add the resulting solution to the pool whilst the pump(s) are turned on, preferably near to the water inlets to aid distribution.
  2. If applying after shock treatment, allow a minimum of 8 hours for shock chlorination to oxidise swimmer wastes from water before application.
  3. Measure the free chlorinated/total bromine level in the water and dose as packaging states.
  4. Split this total amount into 4 smaller doses. Apply 1/4 dose, allowing time to thoroughly circulate (2-3 hours for commercial pools, 6-8 hours for domestic pools) before re-testing chlorine/bromine level and if necessary adding further doses.
