My Discus have been thriving since I started using Discus Buffer. The water pH stabilized and the fish seem more active and vibrant. I still use Discus Trace regularly to maintain trace elements.
Angela Mackay –
The product works as described. pH dropped to the ideal range for Discus. I noticed the water became softer, which matches what I read about the calcium and magnesium precipitation.
Kevin Bond –
After switching to Discus Buffer, my fish showed better color and less stress. The instructions were clear and the product is easy to dose. I recommend it for any Discus keeper.

It lowered pH as expected, but I had to monitor water changes closely. The GH reduction was noticeable, but I’m still adjusting the dosage based on tank conditions.
