Blue Horizons Chlorine Reducer - Tub of 1Kg

Product Information

Following this, you can use the chlorine dosing calculators to work out the required chemical dose to increase the amount of chlorine in the water. Turn off the chlorinator or saltwater chlorine generator, and take any chlorine tablets out of the pool skimmer or floater. These brands will only be Blue Horizons, Deep Blue Pro or Swim Fresh, all established for a long time in the water treatment industry. Using algaecide in your pool is recommended as part of your start-up process each season but also whenever your pool shows signs of developing or established algae. As well as replacing the water you took out, you’ll need to replace the other chemicals you lost during this process to rebalance your water.

p.m) and then add small quantities of pre-dissolved pH Increaser (Sodium Carbonate) or pH Reducer (Sodium Bisulphate). The correct pH level also provides comfortable bathing conditions for the bather as it reduces the chances of irritation occurring. If you’re in no hurry to use the pool, waiting it out is the easiest and most cost-effective approach to lowering your free chlorine level.Calcium hypochlorite is an unstabilised form of chlorine and is the most common form of shock dosing. m. If your water isn’t within this range, continue to use the pH Increaser or pH Reducer, circulate for 24 hours, and retest until you come away with a passing test result. Without use, most pools naturally lose free chlorine at an average daily rate of around 2 to 3 ppm, though this is influenced by things like water temperature, UV exposure, and the cyanuric acid level.

As a result, you should only ever use this approach to make minor reductions in your free chlorine level. If your chlorine level is only a little too high, you can help it back down by simply giving it more “stuff” to sanitize. A free chlorine level that’s higher than that could possibly irritate your skin, eyes, and lungs when you use your hot tub.

So, if you’re starting with completely clean unchlorinated water, then you can set the dosing calculator to a ppm within that range, enter how many litres of water are in your pool, and our calculator will tell you the required amount of stabilised chlorine granules to add. Apply each smaller 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. As with adjusting pH level, it’s hard to estimate exactly how much pH reducer a specific pool requires to reduce its alkalinity level to the appropriate range, therefore this process should be done a bit at a time to get used to how much is needed for your local water supply.
