Seachem Discus Buffer 500g
Seachem Discus Buffer is formulated to help maintain the ideal water conditions for discus fish by lowering pH and softening water, creating an environment similar to their natural habitat. It works by adjusting the pH level to the desired range of 5.8 to 6.8, which is essential for the health and breeding of discus fish, especially in areas where tap water tends to be more alkaline or hard.
Key Benefits:
- pH Stabilization: Discus Buffer helps keep the pH consistently within the optimal range for discus, reducing stress and promoting overall health.
- Water Softening: It reduces water hardness (GH) by precipitating calcium and magnesium, making the water conditions ideal for sensitive fish like discus.

Connor Harris –
Used this in my discus tank after switching to tap water. The pH stabilized quickly and my fish showed less stress. Water became softer and the fish are more active now.
Steven Sutherland –
Good product for maintaining stable pH. I added it weekly and noticed no sudden fluctuations. My discus are thriving and spawning successfully.
Rebecca Payne –
After using this buffer, my tank’s pH stayed between 6.0 and 6.5 consistently. The fish seem healthier and less prone to illness.
