Blue Horizons Chlorine Reducer is used for lowering chlorine or bromine levels in pool water after shock treatment or as a problem solver if the pool has been accidentally 'overdosed' with chlorine or bromine.

Application Instructions

  1. Pre-dissolve the product in a clean plastic container at a maximum rate of 100g of product per 2.2 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 chlorine/total bromine level in the water, then using the dosing table below, calculate the total amount required.
  4. Split this total amount into 4 smaller doses.  Apply each 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.

Daily Dose Rates
Water Volumes To Lower Chlorine* Level By
Litres Gallons 1mg/(ppm) 2mg/(ppm) 5mg/(ppm)
4,546 1,000 23g 46g 114g
11,365 2,500 58g 115g 285g
22,730 5,000 114g 228g 568g
45,460 10,000 227g 454g 1.14kg
68,190 15,000 341g 682g 1.70kg

 *Note: 1mg/l reduction in chlorine = 2.25mg/l of bromine

General Precautions

Dosing

  • Wear eye and face protection and ensure granules are not blown back into your face.
  • Never mix with any other chemicals including cleaning products and chlorine products, as a dangerous reaction may occur.
  • When pre-dissolving product always add to water not vice versa.

Handling/Storage

  • Handle products in a well-ventilated area, preferably outdoors.
  • Wash hands after use.
  • Ensure chemicals do not become damp in storage - store in a cool dry place.
