Sera pH/KH-minus 100 ml – pH and KH Reducer for Aquariums
Sera pH/KH-minus 100 ml is a water conditioner designed to reduce carbonate hardness (KH) and lower pH in a controlled and effective way, creating softer and slightly acidic water conditions.
It is ideal when KH or pH values are too high and need adjustment for species that prefer soft water.
Key features
- Quickly reduces KH and pH
- Controlled acidification of water
- Corrects overly hard or alkaline water
- Helps create soft-water conditions
- Improves suitability for sensitive fish species
- Suitable for freshwater aquariums
How it works
- Lowers carbonate hardness (KH)
- Reduces pH in a gradual and controlled way
- Adjusts water to more natural conditions for soft-water species
- Supports preparation of breeding water
When to use
- High KH levels
- Elevated pH values
- Soft-water species aquariums (discus, angelfish, etc.)
- Breeding preparation
- Overly alkaline tap water
How to use
- Measure KH and pH before use
- Add gradually to the aquarium
- Repeat daily if necessary
- Monitor water parameters after each dose
Recommended dosage
- 5 ml / 20 L of water to reduce approximately 1 °dKH per day
- Repeat daily until desired values are reached
- Avoid sudden changes
- Keep KH above 3 °dKH for pH stability
💡 Example:
- 60 L aquarium → 15 ml per application (gradual adjustment)
