1. What should be filtered, the pool each day?


Most pools should be filtered at least 8 to 12 hours a day (makes the water cycle 2 times) especially during summer. Preferably during the day or when the pool is used.

2. How often to test the pool water?


Depending on the chemicals used and the type of pool (type of construction, size), the frequency of testing varies from day to day. Learning pool over time, create a routine that fits in the pool. But usually one week for private and public daily.

3. If the pool is algae, what should I do?

Depending on the type of algae that has a pool, a strong dose of "Shock" algoktonou proposed to dissolve the bacteria and algae. Then constantly filtering the water clears.

4. How much should I expect to use the pool again after a Shock with chlorine?

Must fall below 3. Usually when Shock with chlorine, the chlorine level will drop below 3 until the next morning.

5. How to keep your pool clean?


The best time to do is test the water in the afternoon, before adding chemicals and again in the morning to make sure that water is suitable for days.

If the pool is used constantly then the test should be performed more frequently during the week.

The strong sun may lower the amount of chlorine in water and therefore the level of chlorine should be monitored constantly during summer.

The color of the pool water should be crystal blue and whatever objects or particles on the surface or in the water should not be ignored. Systematic cleaning of the surface of the walls and the bottom is therefore necessary.

If the pool has Skimmer then systematically cleaning the baskets.

Control of imports and exports of the pool. So if the base operating normally, the skimmer, spouts, broom, overflow, etc.

6. Why is the pool cloudy?


This may be due to several factors:

  1. High pH
  2. Low Chlorine
  3. High levels of total alkalinity
  4. High levels of metals (colorless water)
  5. High levels of algae
  6. The filter needs cleaning or service
  7. Large quantities of tiny particles in water

First check if the filter worked quite a daily basis and then if the levels of chemicals in the pool is ideal.

7. How important is the pH?


The pH of a swimming pool is very important. If it is too high, water may start to damage equipment and even a swimming pool and the pool surface. Low pH causes irritation to eyes and skin. The same can also cause high pH.

8. Using and storing chemicals
  1. Minimize the different types of chemicals you store.
  2. Do not buy more than they would consume in a season.
  3. Most pool chemicals are not well maintained.
  4. Do not store together with other chemicals or other items.
  5. All kinds of acids react dangerously with all types of bromine.
  6. Always use gloves and goggles when handle.
  7. Always away from children.
  8. Place signs at all.
9. Setting the chemical pool


Depending on the results of the test the pool water, you may need to add chemicals to restore the water at ideal conditions for the safety of those who swim and optical clarity.

Must be regularly adjusted levels of PH and chlorine as these tend to change depending on weather conditions and use of the pool.

When the PH is 8.0, the effectiveness of chlorine is only 20% when the PH is 8.5, then goes down to 8%. And respectively when the PH is below 7.0, then the chlorine exceeds 120% (and this is bad).

10. Adjusting the pH


Adjust the pH as the test results of pH. We need to know the cubic pool to calculate the quantity needed. Generally, the pH of the pool tends always to increase. This is a result of chlorination, sweat and urine of those who swim, and the voltage has the nature to balance the pH to 8.5 still water.

High pH: can be reduced by an acid. With the most famous being the dry acid: Sodium Bisulphate.

Low pH: can be increased with an alkaline solution such as the well-known powder soda (Sodium Carbonate).


Caution should be exercised when adding acid to water, and neglect can lead to serious burns. Before adding the acid, should not be anyone in the water and the pump must operate. You will need a plastic bucket to mix the acid with water.

  • Always add acid to water and not water to acid.
  • Add the acid in Cuba and then to pour slowly around the deep end of pool.
  • Never add large quantities at once.
  • Allow the pump to recycle water for at least 4 hours.

An indication from 7.0 to 7.6 is required (7.2 is ideal). If you add too much acid in the pool is likely to mar the walls, the rusty pipes and caps and download the total alkalinity of water.

11. The chlorine in the pool

We are interested in how much available chlorine found in pool water. The chlorine that can act on foreign elements and substances that exist in the pool to keep it clean and safe. A little chlorine has resulted in bacteria and algae, diseases associated with water. Much chlorine can cause eye, nose and skin. Also chlorine in the pool is carcinogenic and our aim is to maintain the level of the minimum required for complete disinfection. We take a sample of water from at least 20-30 cm below the surface and the same distance from the wall of the pool. We test the water in accordance with the instructions of the test kit. Add chlorine according to the results of the test.One such guide: A swimming pool needs about 600 grams of powder chlorine (2-3 tablespoons) for each 50.000 liters of water 2 times a week during a warm summer season.
