The pool water has a milky colour, what can I do?
Cause: Lime precipitates, not filtered particlesSolution: Adjust the pH level to 7.2 to 7.4 (by adding pH-Plus or pH-Minus). If there are suspended matters turn off the circulation pump and remove the flakes on the bottom with the pool cleaner after about 10-12 hours. Lime precipitates in the pool water (turbidity, shimmering white coating on the water surface, etc.) usually disappear shortly after adjusting the pH level and after the addition of a flocculants (while the filter system is running - WARNING: prohibited with cartridge filter systems and filter balls; the filter can stick!). Backwash thoroughly. Clean cartridge filter or replace by a new one.
The pool water is cloudy and dirty, what can I do?
Cause: Faulty filter function, too many organic substancesSolution: Backwashing. If the filter system is calcified, use an acidic filter cleaner. If the filter system is ok, make a shock chlorination, meaning raise the chlorine level of the pool water up to 3 mg/l for a short time. The addition of flocculant is recommended as an additional measure (WARNING: prohibited with cartridge filter systems and filter balls; the filter can stick!). Backwash thoroughly. Clean cartridge filter or replace by a new one.
The pool water is green and the walls are slippery, what can I do?
Cause: Too little disinfectant in the water, algae growthSolution: Adjust the pH level to 7.2 to 7.4 by adding pH-Plus or pH-Minus. Let the filter system run continuously during the first 1-2 days. For disinfection with chlorine: Wipe dead algae from the pool walls. Remove algae from bottom with a brush and an aspirator. Make a shock chlorination, meaning raise the chlorine level of the pool water up to 3 mg/l. The addition of an algae protection is recommended. Backwash thoroughly. The added chlorine has degraded after a few days. Backwash thoroughly. If the water is not clear after 1-2 days, repeat the procedure. Cartridge filter system: Frequently clean or replace the cartridge. Alternatively, empty the pool completely, clean thoroughly and refill. After adjusting the pH value, treat the pool water with algicide to prevent new algae grow.
The pool water is brown, what can I do?
Cause: Iron deposits in the waterSolution: Adjust the pH level to 7.2 to 7.4 by adding pH-Plus or pH-Minus. Add flocculant. (WARNING: prohibited with cartridge filter systems and filter balls; the filter can stick!) Extend the filter runtime, backwash the filter system thoroughly. In the case of a cartridge filter system, clean the cartridge regularly and replace it if necessary.
The pool water has an objectionable odor, what can I do?
Cause: Inadequate chlorine dosing, non-degraded organic substancesSolution: Adjust the pH level to 7.2 to 7.4 by adding pH-Plus or pH-Minus. After a shock chlorination up to ca. 3 mg/l this smell will disappear after a short time.
I get skin and eye irritation in the pool!
Cause: Inadequate chlorine dosing, non-degraded organic substancesSolution: Adjust the pH level to 7.2 to 7.4 by adding pH-Plus or pH-Minus. If there is too little chlorine in the water, increase the chlorine content. If the chlorine content is too high, reduce the dosage or drain the pool water and refill with fresh water. Again, pay attention to the pH value.
What is the best way to add liquid chemical products or granules to the pool water?
Take a bucket of warm water, add the required amount of chemical for your pool and stir well. Then empty the bucket with the mixture evenly into the pool with the filter system switched on (circulating).
Why is there a scale stamped in the lid of cans and bottles?
The lid of our chemical articles also serves as a dosing aid.
Why do I have problems opening the cans or bottles?
Our chemistry must be equipped with a safety lock for the protection of children. This requires some strength to open.
How and where can I access the safety data sheet?
Safety data sheets are stored with the respective chemical article on our homepage. If you still cannot find what you are looking for, please contact us via our form on helpdesk.steinbach.at.
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.
