I’ve used this product for several months in my neon tetra tank. The pH has stayed consistently between 5.0 and 5.2, which is perfect for my fish. The water clarity improved and the fish seem more active. No issues with fish health or behavior after use.

Works well for maintaining a slightly acidic environment. I added it weekly and noticed a steady pH level. My silver dollars are thriving. A little adjustment needed at first, but it settled in after a few weeks.

Great product for setting up a tank for acid-tolerant fish. The water softening effect is noticeable, and the pH remains stable without sudden drops. Easy to use and effective.
