Wanda Avery –
Used Acid Buffer in my planted tank to lower pH gradually. The pH stabilized within a week without harming my plants. No phosphate, which is great for plant growth. Easy to measure and mix with the alkaline buffer. Works well with hard water conditions.
Sean Greene –
Good product for adjusting pH in a planted tank. Took a few days to see results, but the pH dropped steadily. No plant stress observed. The 300g size is sufficient for a 100L tank over several weeks.
