Pool technical maintenance per season
After pool cleaning at the beginning of the season, pool joints should be checked. Renewal of worn joints will help significantly prevent algae formation in pool joints and prevent pool ceramic spills.
It is recommended to check the indoor lighting lamps of the pool and to replace the lamps with faulty lighting. The point to note here is that if there is water between the pool bulb and the pool lamp bowl of the lamps called under plaster pool lamps, complete replacement of the pool lamp body is recommended. In the surface LED pool lighting fixtures, the lamp body is completely replaced.
The pool side sluice channel gratings should be checked and it is recommended to change the worn grates in order not to cause any accidents. If the pool grates are closed at the end of the season, their collection and storage until the new season will significantly extend the life of the pool grating.
Pool pump maintenance in seasonal pools will also extend the life of the pool pump if the pump is removed at the end of the season and stored in a humid middle.
Pool sand filter maintenance, pool filter sands should be checked at the beginning of the season. If there is petrification in the pool filter sands, quartz sands should be replaced with new ones. If there is no petrification in the pool filter sands, the missing sands should be completed and the sand filter sands should be cleaned with the help of a filter cleaner.
How Can Pool Chemical Care Be Performed?
1. Measure the ph value of the water first and make sure that it is in the range of 6.8-7.2. After removing the precipitator, run the system for at least 4 hours and stop the pool until the morning (or at least 8 hours). The use of precipitators causes clouding of the pool water.
2. For shocking to be effective, the ph value must be in the range of 7.0-7.4. For shocking, dose chlorine at least 4 times the average daily dosage or 10 times the proportion of bound chlorine.
3. Do not measure immediately after shock, you will get misleading results. Do not enter the pool before the chlorine level falls below 3 ppm (or at least 12 hours) after freezing.
4. Make measurements with your tester at least 4 hours after chemical removal.
5 Do not dispose of chemicals consecutively. Make sure that there is at least a 4-hour break between chemicals to be used in the same day.
6. As the rate of cyanuric acid (Stabilizer) increases, the disinfecting effect of chlorine disappears.
7. Fresh water should be added to the pool to reduce the cyanuric acid rate. In order to bring 80 ppm cyanuric acid to 40 ppm level, it is necessary to refresh the pool water by half. If the cyanuric acid exceeds 100 ppm, the whole water should be changed. Excess stabilizer may cause turbidity in the pool water.
8. Calcium hypochlorite (powder chlorine without stabilizer) is not used in pool water with an alkalinity value above 120 ppm. Otherwise, it may cloud the water.
9. When using liquid chlorine and calcium hypochlorite, the ph value of the pool water increases. Dichlor (granular chlorine with stabilizer) does not affect the ph rate. When using chlorine (tablet chlorine), the ph value of the water may decrease.
10. When the pH value rises to 8 and above, the chlorine activation in water decreases greatly. When the ph value is below 7, the chlorine is consumed quickly because the chlorine activity accelerates. The ideal ph value is in the range of 7.2-7.6.
11. If chemical additions to the pools are to be made by hand, it must be done in the pool when there is no swimmer and in the evening.
12. Alkalinity of water is important when using pH lowering agents. It reduces 1 kg ph in 100 liters of water with low alkalinity and decreases ph value by 0.2 degrees in water with high alkalinity by 0.1 degrees.
13. Avoid using high rates at the same time while using ph reducers. If it is necessary to use a large amount, first use the half of the first day, calculate the value to be added by measuring again the next day.
14. When excessive amounts of algae killer / inhibitor are used, the water may foam. The algae drug does not disappear in the water like chlorine, fresh water should be added to the pool to reduce its concentration.
15. When cleaning the pool when the pool is empty, it is sufficient to dilute 2.5 kg algae killer in a 100-ton pool and apply it to all surfaces with a brush.
16. Add at least 30 liters of fresh water per swimmer every day.
17. In case of clouding or discoloration in the pool water, apply shock chlorination, continuous filtration and precipitation until the problem is solved. Clear but colored water (blue, green, brown) indicates metal ions such as iron, copper, manganese in the water.
18. A swimmer who enters the pool without shower pollutes 20 tons of pool water, and a swimmer who enters by shower pollutes 2 tons of pool water.
19. The sand filter backwash time should not be less than 5-7 minutes, and the rinsing time should not be less than 30 seconds.
20. To obtain a chlorine level of 1 ppm in pool water (for a 100-ton pool), 1 kg of liquid chlorine, 200 g of 56% dichlor and 150 g of 70% calcium hypochlorite is sufficient.
21. Liquid chlorine quickly loses its active chlorine ratio where it expects. The ratio, which is 12-15% at the production date, may drop below 10% in a short time depending on the storage conditions.
22. Always dissolve the chemicals in another container with plenty of water and add them to the pool. Put plenty of water in the container first and then chemical sheep. Do not do the opposite. It could be a sudden reaction. Chlorine, which is thrown directly into the water in powder form, causes discoloration on the ground and ph reducing powder acids cause the joint fillings to wear out.
23. Do not touch chemicals and test reagents (tablet-liquid) with bare hands. Always use gloves. Keep chemicals out of the reach of children.
24. It is recommended that the pool circulation systems be open all the time. If necessary, you can rest at night when not in use. Never turn off the circulation while the pool is used.
25. The most ideal for pool filling water is mains water. If a source other than mains water is to be used, make sure to make an analysis before filling. Do not use excessively high alkalinity water containing nitrate, iron, copper, aluminum, ammonia. It cannot be removed from the water, the water needs to be refreshed / renewed. Do not use softened water, it will cause ceramic joints to melt.
26. While preparing 56% dichlor (granule) solution, maximum 2.5 kg of chlorine can be dissolved in 100 lt of water. This amount is 1.8 kg for calcium hypochlorite.
27. Liquid chlorine disappears in water from the UV rays of the sun for 4-6 hours, while chlorine with stabilizer is 6-8 hours.
28. If there is deterioration in the water despite the sufficient chlorine level in the measurements, the ph values should be checked, whether there is bound chlorine in the water and the level of cyanuric acid should be checked.
29. In order to reduce the alkalinity value, the ph reducing chemical is used differently. For this purpose, after the pool pump is stopped, the ph reducer is given to the pool slowly (by melting if the powder is acid). (Acid shock application) After half an hour, the circulation pump is started.
30. Do not empty your pool and take winter precautions to protect the pool bowl against ground movements during the winter season and the pool ceramics against external factors. When the season starts, disinfect your pool by draining the water.
Chemical pool maintenance
In the use of pool chemicals, chlorine and ph should not be added to the pool water without testing and analyzing the pool water.
Pool water ph value is one of the most important issues in the chemical maintenance of pool water. It should not be forgotten. Since the pH value is less than 7.0 ppm acidic, abrasions in pool joints, melting in pool handrails and travertines, burning in the swimmer's eyes and redness on the skin occur. At the same time, an increase in chlorine consumption is observed. Pool water pH value should be between 7.2 and 7.6, which are the ideal pH values.
The amount of free-standing chlorine in pool water 1.0 to 1.5 ppm is ideal values.
