I’ve been using these tablets for three months in my small tank. The plants are growing steadily, and I don’t have to worry about CO2 levels. Easy to use and no fish stress. Perfect for beginners.

Works well for my 50-liter planted tank. I added one tablet every 20 liters. Plants show better color and growth. Just make sure to place them in water slowly to avoid bubbles.

Great product for small tanks without a CO2 system. The tablets dissolve easily and maintain consistent CO2 levels. My anubias and java ferns are thriving.
