pH (minus) granules
With pH Minus Granules, you can reliably regulate an excessively high pH level in your pool. An ideal pH level of 7.0 to 7.4 is crucial for clear, skin-friendly water and the full effectiveness of chlorine or algaecide. If the level is consistently too high, it can lead to limescale deposits, cloudiness, and skin irritation. pH Granules quickly restore the correct balance while protecting your pool equipment.

pH (minus) granules
FAQs
Why is my pool water cloudy or has white deposits?
Possible causes:
- Limescale has deposited in the water
- Flocculation particles not completely filtered out
Solution:
- Adjust the pH value between 7.0 and 7.4 (using pH Plus or pH Minus as needed).
- For flocculated particles: Turn off the circulation system and wait approximately 10–12 hours until the residues settle to the bottom. These can then be removed with a floor vacuum.
-
Limescale deposits (white turbidity or a shimmering film on the water surface) usually disappear after correcting the pH value and adding a suitable flocculant.
- Important: Do not use with cartridge filters or filter balls – these can stick together!
- Perform a thorough backwash of the sand filter system . For cartridge filters: Clean the cartridge or replace it if necessary.
Why is my pool water green?
Cause: Algae growth due to insufficient disinfection or filter performance.
Solution:
- Check and adjust pH value.
- Use Bärensteiner Algicide regularly.
- Let the filter system run continuously, backwashing if necessary.
- In case of severe infestation: carry out shock chlorination or shock treatment.
Foam on the water surface
Cause: Organic contamination, soap residue, too high pH value.
Solution:
- Use surface cleaners or skimmers.
- Check pH value and adjust if necessary.
- Filter regularly and use water care products according to dosage.
Limescale deposits on walls or floor
Cause: Water hardness, incorrect pH value.
Solution:
- Adjust pH to 7.0–7.4.
- Use water softeners or anti-limescale products.
- Remove visible deposits with a brush or special cleaning agents.
Turbidity despite a clean filter
Cause: Fine particles, microalgae or chemical imbalance.
Solution:
- Test water: pH, chlorine/redox, alkalinity.
- Use flocculants according to the manufacturer’s instructions.
- Backwash filter thoroughly or replace cartridge.
Rust-brown discoloration
Cause: Metal ions (iron, copper) in the water.
Solution:
- Adjust pH value correctly.
- Use metal removers or special products against metals.
- Run the filter system and check the filter material if necessary.
Cloudiness after rain or strong wind
Cause: Washed-in dirt particles, dust or leaves.
Solution:
- Use skimmers and nets.
- Let the filter system run longer, backwash if necessary.
- Treat water with disinfectant, check pH value.
Unpleasant smell
Cause: bacteria, excess chlorine or organic residues.
Solution:
- Test water: Check chlorine, pH and alkalinity.
- Run the filter system and backwash if necessary.
- Chlorinate pool water or use algaecide.
