Rachel Marshall –
Used this buffer in a 10-gallon discus tank. After adding it, the pH stabilized at around 6.0, which is ideal for discus. The product is easy to mix and works well over time. No fluctuations observed after regular use.
Ella Jones –
Helped maintain stable pH in my discus tank. I added it every two weeks as recommended. The water clarity improved and my fish seemed more active. Slight adjustment needed at first, but it settled after a few days.
