I’ve used this product for three months now and my aquarium’s pH has stayed consistently at 6.5. The water clarity improved and my fish seem more active. No more chlorine spikes after water changes. Very reliable for freshwater setups.

Works well to stabilize pH after new water additions. The chlorine neutralization is effective, and the heavy metal detox effect is noticeable. I still do weekly water changes, but the system is much more stable now.
