Swimming Pool Water Balance

Balancing Your Pool Water

Step 1

To maintain perfect pool water you need to keep the water balanced. Water in the correct chemical ranges prevents algae growth, scale buildup,  cloudy water, equipment damage and even corrosion. Whilst ensuring maximum sanitizer efficiency. The chlorine in your pool water can work most effectively when ideal ranges are maintained. Regular water tests will help you balance your water levels, test strips are commonly used, however we highly recommend once every 6 weeks, to bring a sample of water to our store in Hawkhurst for an accurate water analysis.

Sanitizing Your Pool Water

Step 2

Sanitizers are used to kill bacteria and inhibit the growth of viruses, algae and other organic contaminants that enter your pool water by way of wind, rain, dust and swimmers. The most common pool water sanitizer is chlorine, however some pool owners run on salt systems. Chlorine must be in your pool at all times and maintained at the ideal “free available chlorine” range. Free available chlorine is the amount of chlorine left to kill new bacteria entering the pool. This is what sanitizes your pool continuously. We offer two types of chlorine-based sanitizers – stabilized and unstabilized. Our stabilized chlorine sanitizer contains cyanuric acid, which protects the water from chlorine loss caused by the sun’s ultraviolet rays. Chlorine may be added daily, weekly or monthly depending on the type used. Stabilized chlorines are conveniently dispensed by placing them in a skimmer basket, chlorinator or floating dispenser. While unstabilized chlorine should be added directly to the pool water.

Shock Your Pool Water

Step 3
To keep your water clear your should shock your pool water weekly. Bacteria and organic pollutants can build up and resist normal chlorination resulting in contaminated and cloudy pool water. To break up these contaminants it is necessary to raise the chlorine level quickly by shocking your pool. Shocking helps to rejuvenate pool water by burning off chloramines. Chloramines’ is the chlorine in your pool that has already worked to kill algae or bacteria and now has become ineffective. Chloramines in your pool cause strong chlorine odors, burning eyes when swimming, and prevent the chlorine in the pool that still has sanitizing capabilities (free available chlorine) from doing its job.
It is best to apply shock in the evening so it can work overnight and be down to normal levels by the next day. Be sure to run your filter for at least one hour after shocking. In some cases, you may need to shock more than once a week.

Algae Control

Step 4
Algae are microscopic aquatic plants constantly being introduced into the pool water by rain, wind, or other means. There are numerous varieties – some are free floating, some grow on walls and other surfaces. If not kept under control, algae can discolor your pool water, clog your filter, cause unpleasant odors and produce slimy, slippery walls and floor. Algae growth is common when the sanitizer level in the water is low or neglected.
Algaecides are used to prevent growth and treat existing algae that survive general sanitizer dosages.

Chemical Types


Fi-Clor chlorine-based sanitisers, available as a granular or tablet product, deliver chlorine in a solid form that is safe for pool owners to use, but when mixed with water releases a powerful and effective dose of free available chlorine.

Shock Treatment

Superfast Shock & Sanitiser products are made from calcium hypochlorite and contain no stabiliser, which when present in excess, may inhibit chlorine activity. Superfast Granules dissolve rapidly when added to water and produce an impressive 78% available chlorine.

Ideal for indoor and outdoor pools, with both granular and tablet versions helping to balance the water in soft water areas.

We are a registered Fi-Clor pool care center!

Water Balance

Algae growth, eye and skin irritation and cloudy water are all common problems associated with unstabilised water.

For water to be in balance, the pH, total alkalinity and calcium hardness should all be within certain limits – if not, the efficiency of disinfectant, flocculent and other treatment products are inhibited. Regular testing of pool water will ensure the correct remedial action can be administered.

With our extensive range of corrective products the water balance can be easily maintained.

Prevent or Cure

Even when pool water is disinfected and balanced it is still affected by the bather load, wind, air pollution, insects, surrounding vegetation and the ambient temperature. These factors can cause the water to become cloudy or turn green. Fi-Clor offers a complete range of Prevention or Cure products that not only solve these problems but also prevent them from recurring.
