I’ve used this block in my 100L aquarium for three months now. The water has stayed stable, and I haven’t had any ammonia spikes. It’s easy to place and works quietly in the tank. No noticeable changes in fish behavior.

The block fits well in my pond and has helped reduce acid levels during heavy rain. I noticed a difference in water clarity after a few weeks. It’s a simple solution for maintaining pH balance.

Great product for beginners. I didn’t have to worry about water testing after installing it. The ammonia levels stayed low even during fish feeding. Works reliably in a 120L tank.
