TROPICA CO2 System 60
Most aquarium plants do not thrive without CO2 fertilization – but algae does! So without extra CO2, your new plants can suffer and algae will take over your tank.
- A simple and inexpensive way to supply extra CO2 to the plants in your aquarium
- Easy to install, use and maintain
- Suitable for starter-sets, where even small amounts of extra CO2 will make a positive difference for the plants

I bought this for my 60L tank with new plants. It’s easy to set up and the CO2 delivery is steady. My plants are growing well and algae has not taken over. I only vented it once a week as instructed.

Works as expected for my 40L tank. The daily dose is just right. I didn’t have to adjust anything. The system is simple and reliable for a beginner.

Great value for the price. Plants grew noticeably after a few weeks. The instructions were clear and the weekly venting is straightforward.
