Oxidising Pool Water

Swimmers, young children and rain all introduce waste products into your pool water.  As these waste compounds build up they become a source of food for bacteria and algae encouraging their growth and making your pool water unhealthy and cloudy.  Organic wastes will react with chlorine creating chloramines (combined chlorine) that has an unpleasant pungent odour and is irritating to eyes and nose.  Oxidising or shock dosing destroys chloramines and organic wastes helping to keep your pool comfortable for bathers.

Chlorine Demand

Chlorine demand is at the route of many pool water problems and could be described as the amount of chlorine necessary to destroy bacteria, algae and other organic wastes.  The only way to overcome chlorine demand is to keep shocking the pool until its ‘hunger’ for chlorine is satisfied, this is straightforward to do but can take a few days depending what the level of demand is.  Shock dose the pool using sufficient Blue Horizons Granular Shock or Shock ‘n’ Floc Granules to increase the chlorine level by 10mg/l, after 24 hours check the chlorine level using your test kit if the chlorine level is 5mg/l or lower then it is likely that the chlorine demand has not yet been satisfied, so repeat the shock dose.  Keep repeating this process until after 24 hours the chlorine remains above 5mg/l.  Then wait for another 24 hours and check the chlorine level again, if it is still around the 5mg/l level then you have probably satisfied the waters ‘hunger’ for chlorine and satisfied the demand.

Top Tip: As soon as possible after a thunderstorm shock dose your pool with a 5mg/l dose of Blue Horizons Granular Shock Granules or Shock ‘n’ Floc Granules.  The reason for this is that lightening creates nitrogen in the atmosphere and the rain washes this nitrogen into your pool.  Nitrogen is plant food and algae thrive on it, so pool water can quickly turn green after a thunderstorm, a shock dose of chlorine can help prevent this.

Regular Oxidation

Regularly oxidising pool water, ideally weekly, will pay dividends in the prevention of pool water problems.  Within the Blue Horizons range there is a selection of products that are ideal for the regular oxidation of pool water.

Blue Horizons Pool Fusion

The ultimate product for regular oxidation, Pool Fusion is a blended product that not only destroys organic wastes and eliminates chloramines but also clarifies the water to help achieve sparkling pool water that looks great and is comfortable for bathers.  Supplied in pre-measured sachets Pool Fusion is the easiest oxidiser to apply as you simply cut the corner of the sachet with scissors and broadcast the contents over the waters surface, no pre-dissolving is required.  One 350g sachet is sufficient to treat pools up to 45.45M³ (10,000 gallons).

Blue Horizons Non-Chlorine Shock

A granular product that is ideal for the regular oxidation of pool water as it will destroy organic waste and chloramines without increasing the chlorine level, meaning that you will be able to swim shortly after application.
