Seachem Discus Buffer
Discus Buffer helps to replicate the ideal Discus environment (low pH & low GH (General Hardness)). Discus Buffer will lower pH and keep it lowered. Discus Buffer also softens water by precipitating calcium and magnesium. Use Discus Trace to restore the proper level of trace elements and feed NutriDiet Discus Flakes for thriving, healthy Discus.
Neutral Regulator and Discus Buffer can be used in combination to achieve the desired pH when performing water changes or adding top off water. The ratio chart below is designed for RO water where there is generally no buffering capacity.
| Water Type | Discus Buffer (ml) | Neutral Regulator (ml) |
|---|---|---|
| RO Water | 1 | 1 |
| Tap Water | 2 | 2 |
FAQ
Can Discus Buffer be used with tap water?
Yes, Discus Buffer can be used with tap water. However, the recommended ratio may vary depending on the water’s natural buffering capacity. For tap water, use 2 ml of Discus Buffer and 2 ml of Neutral Regulator.
Does Discus Buffer affect trace elements in the water?
No, Discus Buffer does not affect trace elements. Use Discus Trace separately to maintain proper levels of trace elements.
How often should Discus Buffer be added?
Add Discus Buffer as needed during water changes or when topping off the tank, especially when using RO water or when the pH rises.

Harry Scott –
My discus have been much healthier since I started using Discus Buffer. The water pH stays stable and the fish seem more active. I combine it with Neutral Regulator for better results during water changes.
Jennifer Greene –
Works well with RO water. I noticed a significant drop in pH after adding the buffer. The fish are less stressed and the water clarity improved.
Molly Skinner –
I used it regularly during water changes and my discus have not shown any signs of stress. The calcium and magnesium levels dropped as expected, which is perfect for their needs.
Colin Blake –
It works but I had to adjust the dosage based on my tap water. The pH dropped faster than expected, so I now monitor it more closely.
