Test: What type of carer are you?

Cleaning your swimming pool

To ensure hygienically clean water care it is necessary to clean the pool regularly, whereby the pool should be cleaned while empty at least once a year. This applies to both outdoor pools and indoor pools, because regardless how clear the water looks, the sides and bottom must be cleaned of lime and dirt deposits in order to remove micro-organisms (bacteria and algae).

  • Basic facts about water treatment
    Circulation and filtration of the water (physical water treatment) and the addition of water care products (chemical water treatment) are fundamental prerequisites for effective treatment. These physical chemical water treatments mutually enhance each other and both are equally important for effective care. The principle of the aquifier system is shown in the illustration. Circulation and filtration alone do not however keep the water clear and germ-free. This is why chemical water treatment is also indispensable. Bacteria, fungus and viruses are only killed by disinfectant, algae growth is only properly checked using algaecides, and numerous very fine particles and substances that cause opaqueness can only be removed by flocculation. Every swimming pool owner must also give his pool chemical care so that he can bathe in perfectly hygienic water. To be able to properly care for your pool it is essential to have some basic knowledge of pool water treatment and how various care products work. These will be explained below. On average this will take you 10 minutes a week and will soon become quite routine.

  • Physical water treatment
    If the water flow through the pool is good, the filter will catch most of the larger particles. We generally recommend that the filter pump is kept running until all the water in the pool has been circulated at least 2-3 times a day. As a rule this corresponds to a filter runtime of 6-8 hours a day. A longer filter runtime is even better. If you use a sand filter you must give it a backflush every week. This also replenishes your pool water with fresh water. What works automatically when a sand filter is given a backflush, also works for other kinds of filter. These also have to be cleaned and at least 3% of the water has to be replaced by fresh water every week. Any foreign bodies still in the water despite all this are either removed manually using a scoop or they are vacuumed up using an automatic bottom vacuum (automatic pool cleaner).

  • Chemical water treatment
    Chemical water treatment involves 4 different steps: 1. pH regulation 2. Water disinfection 3. Algae prevention 4. Flocculation There are four different care programmes for disinfecting your pool water and every pool owner can choose whichever they prefer:

  • Thorough cleaning (spring clean)
    For cleaning your empty pool you should always use Decalcit Super. This highly effective, viscous cleanser has been specially developed to remove lime and other soil deposits while maintaining the highest degree of material protection. It is applied with a brush and then rinsed with water after cleaning. If your pool is made of sensitive foil or plastic, Adisan is also suitable for thorough cleaning.

  • General cleaning (maintenance cleaning when the pool is full)
    General cleaning should also be done regularly because air pollution and constant use for bathing results in mildly fatty and sooty soiling. Adisan is good for removing such residues. Randfix was specially developed for dirt, fat and soot scum at the level of the water surface. The best way to clean is to use a suitable fleece (Randfix care set) when the water level is lower, e.g. during back flushing. Randfix is suitable for all pool surfaces such as tiles, foil, polyester, etc. Since the product is viscous this makes it ideal for vertical surfaces (pool sides). Take care when using cheap household cleansers. They introduce foreign particles into the water that can lead to cloudiness, foam or the growth of algae and can attack some surfaces, e.g. foil.

  • When the sides of the swimming pool get slippery
    Problem: Green, cloudy water, bottom or sides are slippery, algae Possible cause: Algae growth (especially during stormy weather) Not enough algaecide in the water Water contains phosphate (food for algae) Remedy: Measure pH and if necessary set to 7.0 - 7.4 Mechanically brush algae off the bottom and sides, loosen it up and vacuum as completely as possible. Back flush or clean the filter When using VariTab: Add the double amount once Give a chlorine shock with 1 chlorineiklar/m or 25 g chlorifix/m Let the circulation pump run continuously for at least 24 hours With sand filter systems: Add an additional Superflock flocculent cartridge into the skimmer for removing clouding Preventative measure: Afterwards add the double quantity of algaecide into the pool water (Desalgin, Desalgin Jet) Regularly use a Superflock flocculation cartridge for removing phosphate from the water In the case of obstinate problems: Extra filter clean using FilterShock

  • Pool sidewalls feel rough
    Problem: The sides of the pool feel rough, the water is cloudy or milky Possible cause: Lime is precipitating because the pH or the temperature are too high Remedy: First brush the lime from the bottom and sides mechanically and remove lime deposit from the bottom using a vacuum cleaner. If the lime cannot be removed mechanically: drain the water, clean with Decalcit Super To prevent further lime precipitation, add Calcinex to the pool water. When filling the pool anew, always add Calcinex while the pool is being filled.

  • Black spots on pool foil, green hairs
    Problem: Black spots on pool foil, green hairs Possible cause: Copper in water, caused for example by corrosion or cupriferous algaecide (BAYROL algaecides do not contain any copper) Remedy: Set pH to 7.5-7.8 Add Superflock for removal of copper Request our special lab data

  • Bleach spots
    Concentrated disinfectant acts as bleach, so you should not drop slow-dissolving disinfectant tablets straight into the pool but use a dosage float or place it in the skimmer. Quick-dissolving chlorine tablets (Chloriklar) are best dissolved in the skimmer (with running pump!). This avoids bleach spots caused by small chlorine particles which could trickle through the net of the dosage float. When using granules that are dosed straight into the pool there is no danger of bleaching because the substances used dissolve immediately. To be on the safe side, the circulation should be kept running and the granules should be added at several places around the pool. Chlorine particles on clothing will bleach the material if it comes into contact with moisture.

  • Filter maintenance
    We always recommend backwashing at least once a week in order to remove the dirt that has collected in the filter medium. If the water is hard, lime will be deposited in sand filters despite regular backwashing. In extreme cases the deposit can almost fully block the filter medium and consequently seriously reduce the filter effect. As a preventative measure we therefore recommend you descale and clean the filter 3-4 times a year using Decalcit Filter. After carrying out a backwash, add 300 - 500 g of Decalcit Filter in the skimmer, set the filter control to "Filter" and switch the pump on briefly and then switch it off again straight away so that the Decalcit Filter reaches the filter tank. Let it work overnight and then give it a good backwash. Effective disinfection and removal of cloudiness by flocculation requires that the sand filter system is working perfectly. Generally: Replace filter sand every 2 - 3 years! BAYROL has done intensive research into the relationship between water quality and filter condition and found out that in practice, every second filter is either soiled or contaminated. This has a serious negative effect on the effectiveness of the disinfectant used. The disinfectant is then effectively wasted as far as killing germs is concerned, and no longer effectively disinfects the pool water. To combat this, the BAYROL research department have developed Filterclean Silver, a patented filter granulate that prevents the build-up of germs and bacteria in a place hard for the disinfectant to reach - right inside the filter. This guarantees you long-lasting high water quality and provides long-lasting (2 - 3 years) disinfection of the filter area. Next time you change your filter sand, have your BAYROL dealer fill 40% of it with Filterclean Silver instead of silica sand and make sure that you backflush the filter for 5 minutes before you switch it on for the first time. The material is then well mixed and will give you a germ-free filter system for the next 2 to 3 years. The most frequent cause of cloudy and green water or generally poor water quality is a soiled or contaminated sand filter. This particularly occurs in pools where the backflush speed of the sand filter is insufficient. The solution to these problems is the new FilterShock, a chlorine-based granulate for cleaning and disinfecting filters. FilterShock has a double effect: it cleans any organic dirt left in the filter, and effectively kills germs with its disinfecting impact. Adding FilterShock is recommended at the start of the season and when any problems arise.

  • Tips for the start of the season
    Swimming pool manufacturers recommend keeping outdoor pools filled during the winter. So in these cases the question at the start of the season is whether you should treat the "wintered" water or refill it with fresh water. For outdoor swimming pools BAYROL recommends a complete water change once a year, and for indoor pools every 2 - 3 years. The best time to change the water in outdoor pools is in spring because after the winter you will have to give the pool a spring clean anyway. If the pool is empty and free of dirt and lime, check the filter and fill it up with water from the tap. First set the pH (7.0 - 7.4), and then begin with a thorough disinfection or chlorine shock. You can then continue with normal care 3 days later. Remember that when you refill the pool, the pH will rise rapidly in the first few days and must therefore be checked more frequently and if necessary reduced using pH-Minus.

  • Holiday care
    If you do not have an automatic pool water treatment dosage system and are away for more than 8 days you must ensure that you have a store of agents for disinfection and algae prevention for while you are away. Ideally you should cover the pool with a tarpaulin but not switch off the automatic pool circulation, and let it continue to run daily (half as long as usual). If you have a sand filter we recommend the following procedure for when you are on holiday: Give it sufficient backwash, set the pH to 7.0 - 7.4 and then it is best to place a BAYROL Multibloc (for 30 - 50 m water) in the skimmer. The Multibloc will last for about 3 weeks. If you have a cartridge filter: Clean the filter, check the pH (7.0 - 7.4) and then depending on the size of the pool, place several Chlorilong tablets in the dosage float. By reducing the size of the dosage slit you will provide the pool with disinfectant for a good 3 weeks. Don't forget to add twice the usual amount of Desalgin, Desalgin Jet or Bayroplus. Even if the pool water looks perfectly all right when you return from your holiday you should still first give the filter a good backwash or wash it out. Use FilterShock Tab if necessary

  • Outdoor pools in winter
    Swimming pool manufacturers recommend keeping outdoor pools filled during the winter. The advantages: keeping the pool filled with water counteracts the pressure of slipping earth (pressing in the sides of the pool) or any "floating" of the pool when the groundwater level is high in spring. A filled pool is also less exposed to the effects of the weather, and cannot be damaged by any objects falling into it. Adding Puripool, a special agent for the duration of the winter, also has an additional advantage: this will prevent lime deposits or algae growth from the very start and this will in turn make the spring cleaning much easier and involve less effort. Tip: Even if you have already added Puripool to the water, you can still bathe in it without any problems. Note the following for winter: 1. Set pH (7.0 - 7.4) 2. Keep the circulation running when you do a chlorine shock, so that existing impurities do not "hibernate" 3. When the pool is out of use, ensure the water level is below the ducts 4. Spread the proper dosage of Puripool over the whole pool 5. Empty outside pipes 6. Place an ice buffer to compensate for ice pressure in the pool
