How to take care of your swimming pool?
The article below will help you keep your water crystal clear and free of all unwanted microorganisms, such as pool algae.
First of all, please be aware that swimming pool water treatment chemicals are chemicals that can harm your health in concentrated form.
For this reason, please respect the following rules:
- Store the agents in their original packaging in a dry place and keep out of the reach of children.
- Under no circumstances should two different chemicals be mixed directly without diluting, as this may result in fire, explosion or the release of poisonous gas.
- always follow the instructions on the product labels.
How to proceed with the pool BEFORE THE SEASON?
In the spring, before the swimming season, you need to clean the pool, remove leaves and other unwanted items (using pool vacuum cleaners or pool nets). Clean the sides of the pool with agents specifically designed for this purpose: Randrani A gel or Randrani S gel. Then fill with water and start the chemical treatment.
The first step in this process is pH correction. We do this by means of pH minus or pH plus depending on the pH level of the water.
- The required pH value in communal pools is between 7 and 7.4 and the same value is recommended in family pools. This is very important for the following reasons:
- if the pH value is higher than 7.4, it proportionally reduces the effect of disinfectants - the higher the pH, the more chlorine or other disinfectant must be added to the water to obtain the same bactericidal effect.
- the same is true for algae multiplication - the higher the pH, the more algae in the pool will grow and the more treatment agents are needed to restore the water to its original purity and clarity.
- if the pH value is lower than 7, the metal parts of the swimming pools will corrode: mainly stainless steel ladders.
- people with sensitive skin may have problems (irritation and redness, allergic reactions) if the pH of the water is lower than 7 or higher than 7.4.
|above PH 7.4
- skin intolerance
- eye irritation
- calcium precipitation
- reduction of disinfection efficiency
- deterioration of coagulation
|PERFECT VALUE (pH 7.0 to 7.4)
|below PH 7.0
- corrosion of metal parts
- attacking pool joints
Once we have the correct pH value, we move on to the next step, which is to prevent the growth of algae in the water. For this purpose, we use Algen, or its stronger version - Algen super. Pour the amount of the agent measured according to the instructions on the label into the skimmer with the water circulation on.
The next step is to coagulate microscopic impurities rising in the water. For this purpose, we use the Superkalga agent. Pour the measured amount of the agent into a watering can, fill it with water and evenly distribute the prepared solution over the entire surface of the water. Then we should turn on the water circuit and filter until the water becomes crystal clear. Remove some of the dirt that falls to the bottom with an underwater vacuum cleaner.
The final stage of treatment is the disinfection of the pool water. For this purpose, we use fast-dissolving agents containing chlorine - Chemochlor CH granules or Chemochlor T tablets. Put the tablets into the skimmer with the circulation on, while the granules are dissolved in a bucket and the solution poured into the skimmer.
Attention! Do not throw tablets or granules directly into the pool, the material from which the pool is made (plastic, foil) will become discoloured.
How to deal with the swimming pool IN THE SEASON?
Thus, we have completed the preliminary water treatment in the pool. Leave the filter pump turned on until the water becomes crystal clear and the amount of chlorine in the water drops to 0.5 mg / liter. At this point, the water is ready for swimming.
Now it will be necessary to maintain the water in such a way that due to external influences (precipitation, dust and other pollutants, pollution brought by swimmers) the water quality does not decrease.
For this reason, it is very important to filter the water and measure the quality of the water.
A very easy-to-use device for measuring the pH value and the amount of chlorine in water - a photometer - is for this purpose.
As a reminder, the pH value should be between 7 and 7.4 (ideal is 7.0) and the amount of chlorine in the water should be between 0.3 and 0.6 mg per liter. A lesser amount allows algae and microorganisms to multiply, whereas exceeding the upper limit may cause skin irritation and allergic reactions in some people.
To maintain the necessary concentration of chlorine, we use slowly dissolving regular chlorine tablets Chemochlor T200 or multifunctional tablets, which, in addition to chlorine, also contain appropriate amounts of anti-algae agent and pollutant coagulation agent. We apply these agents with the help of special dispensers called floats or we put them into a skimmer. Each day the amount of chlorine in the water should be monitored and its amount adjusted. If the pool is not equipped with a dispenser (float), it is recommended to use small 20 g of chlorine tablets, which you put in the skimmer.
When using conventional chlorine tablets, you also need to dose the water with the Algen or Algen Super anti-algae agent and the agent for purifying the water from fine colloidal impurities of Superkalga in the amounts specified on the labels.
Note: Doses of chlorine compounds are given on the label as an approximation, always be guided by the results of measurements obtained from the photometer.
Further recommendations: In addition to water treatment with filtration and chemicals, the pool must be mechanically cleaned. For this purpose, there are underwater vacuum cleaners, special brushes and nets to catch various contaminants floating on the surface or falling to the bottom. After some time, a layer of greasy dirt will form on the edge of the water. Randrani Super, Randrani A gel or Randrani S gel are available for its removal.
Pump and Filter Running Time: Usually it is enough to run the pump twice a day, running time 2 to 4 hours depending on pool size, pollution degree and pump performance. In the period of prolonged heat waves, it is recommended to extend the filter and pump operation time twice. To achieve a long-lasting effect of water purity, it is recommended to double-chlorinate the water every 2 or 3 weeks, the so-called shocking technique. Thanks to this process, microorganisms that have become accustomed to the usual concentrations of chlorine are eliminated. The chlorine dose should be used in the same amount as in the preparation of the pool in the spring. Chlorine concentration should be in the range of 2 to 3 mg per liter of water. Chlorine shocking should be performed with quick Chemochlor tablets or with Chemochlor CH granules, preferably in the evening, bathing is allowed only when the amount of chlorine drops to 0.6 or lower. The process can be accelerated by adding Antychlor according to instructions.
What to do when the water turns green due to the proliferation of algae?
- First, measure the pH value, if the value is higher than 7.2, it is recommended to lower it to 7 - 7.0.
- Add Algen super to the water in the amount as in the spring for the first dosage
- Add chlorine tablets or chlorine granules to the water in the amount as in the spring for the first dosing or in case of under-chlorination with shock
- Filter continuously until you get crystal clear water.
How to proceed with the pool AFTER THE SEASON?
In the autumn, drain the water from the pool until the level is just under the nozzles, and pour Winterkreservant into the rest of the water, which prevents the growth of algae and prevents dirt from sticking to the walls and depositing mineral deposits on the walls, thus facilitating the cleaning of the pool in spring. The next step is to drain the water from the skimmer, piping and filter, and disassemble the pump, which is recommended to be stored in a frost-free place.
