Removing algae in the pool: This is how it works with algicide
Algae are a breeding ground for bacteria and the cause of slippery, green walls and floors. The use of disinfectants such as chlorine is not completely sufficient to stop algae growth, as algae develop resistance to chlorine over time. The optimum chlorine level of 0.3 to maximum 0.6 mg/l should never be exceeded. In order not to have to increase the chlorine content - which is irritating if the value is too high - algaecides are a proven aid to inhibit the growth of algae and remove turbidity substances. Steinbach aqua correct products against algae are produced in Austria and tested according to strict quality standards. The vicious circle of microscopic contaminants can be illustrated as follows: On hot days, the high temperatures provide the perfect conditions for micro-organisms and pathogens such as bacteria, viruses, fungi or parasites to multiply, which are food for algae that grow in succession and are responsible for green, slippery walls. Algae in turn are the perfect breeding ground for bacteria, viruses and fungi. The more people that swim or bathe in the same pool and the warmer the temperature of the pool water, the more likely it is that larger quantities of small contaminants are brought into the pool, which multiply and promote algae growth. In addition to the use of disinfectants, algicides are used to remove algae. Since the use of anti-algae agents does not cause algae to form, there is no damage to the pool and its lifespan is increased.
Tip: Algae like heat and light. By using a cover, you not only prevent the penetration of coarse dirt, but also direct sunlight, which promotes algae growth.
Note for green water, algae growth, slippery walls
If the bath water turns greenish, there is too little disinfectant in the water circuit. Algae growth is the result of too low a dose of chlorine or active oxygen. Adjust the pH value to 7.2 and let the filter system run continuously for the first 1 to 2 days. Proceed as follows for disinfection with chlorine: Wipe off any dead algae from the pool walls and remove it from the floor with the pool brush and a vacuum cleaner. Carry out shock chlorination, i.e. increase the chlorine content of the pool water to 3 mg/l for a short time. As the next step, add algaecides and carry out a backwash of your filter system. The added chlorine will have decomposed after a few days. If the water is still not clear after 1 to 2 days, repeat the process. In the case of a cartridge filter system, the cartridge must be cleaned regularly or replaced if necessary.
Note: Special winter care products protect the lowered water of your pool from algae growth at cold temperatures. As with all chemical additives, please always observe the warnings.
