I’ve used this buffer in my planted tank for several months. The pH stays stable between 7.6 and 7.8. My plants are thriving and there’s no sign of stress. Easy to measure and mix. Works well with the acid buffer for fine-tuning.
Cameron Mackay –
Good product for maintaining alkaline pH. I added it gradually and noticed a steady rise in pH. My shrimp and plants seem more active. A bit pricey, but effective.

Used it after a water change that dropped the pH. The buffer raised it smoothly without any spikes. My aquarium inhabitants stayed calm. No plant damage observed.
