Used this buffer for my angelfish tank and noticed a steady pH level after a week. The water clarity improved and my fish seemed less stressed. Easy to measure and mix. Would recommend for Amazon Basin species.

Good product for maintaining stable KH in a low pH setup. The instructions are clear and the buffer works as expected. Slight delay in shipping due to special order, but the results are consistent.

Perfect for my neotropical fish setup. The pH stayed stable even during water changes. No algae issues since using it. Simple to use and effective.
