Product Information
Full details
Seachem Discus Buffer is designed for freshwater aquarists dedicated to keeping acid-loving species, particularly Discus, by lowering and stabilizing aquarium pH. It effectively softens water by precipitating calcium and magnesium while providing a stable, phosphate-buffered environment. While it is highly effective at creating a specific chemical profile, users must be diligent about monitoring their water parameters, as consistent dosing is required to prevent pH swings when performing water changes.

Extended Product Information
FAQs
Can I use this for my goldfish?
No. Goldfish prefer neutral to slightly alkaline, hard water. Using this product will create an environment that is detrimental to their health.
How often should I dose?
Dose daily until the target pH is reached, then dose monthly or whenever you perform water changes to maintain the levels.
Does this replace water conditioner?
No, you must still use a dechlorinator like Seachem Prime to remove chlorine and chloramines from tap water before adding the Discus Buffer.
Is this safe for live plants?
Yes, but be aware that some plants may struggle in very soft, acidic water, and the phosphates in the buffer may alter your fertilization requirements.
What is the benefit of adding Seachem Discus Trace?
Discus Buffer removes essential minerals as it softens the water; Discus Trace replenishes these minerals to prevent long-term health issues in your fish.
Troubleshooting
The pH level is not lowering despite dosing.
Your water likely has a very high KH (Carbonate Hardness). Perform a larger water change with RO (Reverse Osmosis) water to reduce the baseline mineral content before dosing the buffer.
Algae bloom occurring after regular use.
The phosphate content in the buffer may be fueling algae. Ensure your lighting duration is moderate and increase your frequency of routine tank maintenance.
Pros and Cons
Pros
- Significantly simplifies the process of creating soft, acidic water
- Provides excellent long-term pH stability for sensitive fish
- Effective at softening water by removing calcium and magnesium
- Easy to dose with a standard teaspoon measurement
Cons
- Phosphate-based formula may contribute to algae growth in high-light tanks
- Requires careful measurement to avoid rapid pH drops
- Needs complementary supplementation of Seachem Discus Trace
- Not suitable for tanks containing hard-water fish species
Setup, Compatibility & Care
To ensure success, always add Seachem Discus Trace to the water after using the buffer. Because Discus Buffer removes minerals, your fish will eventually suffer from mineral deficiencies if the trace elements are not replaced.
- Testing: Always keep a reliable liquid-reagent pH test kit on hand.
- Dosing: Use 1 level teaspoon per 40-80L of water.
- Mixing: Dissolve the buffer in a cup of aquarium water before pouring it into the tank or the filtration return.
- Compatibility: This product is fully compatible with most freshwater community tanks that house species naturally found in soft, acidic rivers, such as Neon Tetras or Corydoras. Do not use in tanks containing African Cichlids or other species that require hard, alkaline water.
