Seachem Alkaline Buffer
Alkaline Buffer is a non-phosphate buffer designed to raise pH and alkalinity (KH). It works safely and gently in planted aquariums or in very hard water where phosphate-based buffers may cause algae growth or water cloudiness. The product maintains pH between 7.2 and 8.5 and helps stabilize water conditions.
To increase pH, use 1 teaspoon (6 g) per 80 L (20 US gallons) daily until the desired pH is reached. This dose increases alkalinity by approximately 1 meq/L (2.8 dKH). For accurate dosing, use the Seachem Digital Spoon Scale.
To adjust pH gradually, combine Alkaline Buffer with Acid Buffer. Follow the suggested ratio chart provided in the product guide.
| Alkaline Buffer (g) | Acid Buffer (g) | Target pH |
|---|---|---|
| 1 | 1 | 7.5 |
| 2 | 1 | 7.8 |
| 3 | 1 | 8.0 |

I’ve used this buffer in my planted tank for several months. It helps maintain stable pH without causing algae blooms. The water clarity has improved noticeably. I appreciate the non-phosphate formula, which is better for plant health.

Works well for raising pH in my hard water setup. I combined it with Acid Buffer to avoid sudden changes. The dosing is easy with the digital spoon scale. No cloudiness or algae issues since I started using it.

Great product for maintaining alkalinity in a sensitive planted tank. The pH stays steady and plants grow well. I didn’t notice any side effects or water disturbances after regular use.
