I’ve used Seachem Prime for over a year in my 100-liter freshwater tank. It’s been essential during water changes and when setting up new fish. The water stays stable, and my fish show no signs of stress. Works well with my filter and cycling process.

After switching from a cheaper conditioner, I noticed a significant improvement in water quality. My new betta fish stayed healthy even after a major water change. The ammonia levels dropped quickly, and the tank felt more balanced.
