Product information
pH + (plus) granules, kg ,
Alkaline granules to increase the pH-value
USAGE: Water care product. The pH-value of the water is one of the most important factors for an optimal effect of swimming pool disinfectants. pH - (minus) granules are used to lower the pH-value and pH + (plus) granules are used to increase the pH-value. The optimal range for the pH-value is between 7.0 and 7.4. Deviations increase the necessary dosage quantities of other products, or reduce their effect. The measurement can be taken with test strips or tablets.
For private swimming pools only.
DOSAGE: To increase the pH-value by ca. 0.1, add 100 g (ca. 75 ml)/10 m³ to the pool water. The addition should be done in small portions before the inlet nozzle or by prior dissolution.
FAQs from category Adjusting of the pH value:
The ideal pH value is between 7.0 and 7.4. If the pH value is too high (above 7.4) the water tends to form lime deposits (turbidity of the water). Eye and skin irritation could occur. The disinfection effect could also be reduced. If the value is too low (below 7.0), the water becomes increasingly corrosive. Odour nuisance and irritation of the mucous membranes may occur. We recommend measuring the value twice a week. For pH regulation we recommend 'ph + (plus) granules' or 'ph - (minus) granules'.
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).
