Algezid Premium liquid, 5,00 l, UN3082, Aquatic Acute 1, Aquatic Chronic 2
USAGE: Water care product for algae growth prevention. Highly concentrated and foam-free algal control agent with clearing effect and long-term effect. Prevents algal growth in the swimming pool, helps removing turbidities and clears the swimming pool water.
For private swimming pools only.
DOSAGE: Before adding Algezid Premium liquid, adjust pH-value to the optimal range of 7.0 - 7.4. For initial dosage add 25-50ml/10m³ and then weekly 10ml/10m³ for indoor swimming pools and 20ml/10m³ for outdoor swimming pools near the inlet nozzles to pool water. In the case of heavy algal growth (green traces), up to 300 ml/10m³ can be given into the pool after a shock treatment. For algal growth prevention, the pool wall can be pretreated undiluted with a sponge before filling the pool.
FAQs from category Algicides:
Cause: Lime precipitates, not filtered particles
Solution: 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.
Possible Causes: Faulty filter function, too many organic substances
Solution: 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.
Possible cause: Too little disinfectant in the water, algae growth
Solution: 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.
Possible cause: Iron deposits in the water
Solution: 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.
Possible cause: Inadequate chlorine dosing, non-degraded organic substances
Solution: Adjust the pH level to 7.0 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.
Possible cause: Inadequate chlorine dosing, non-degraded organic substances
Solution: Adjust the pH level to 7.0 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.
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).
