Planted Nano Aquarium - Can you succeed with DIY CO2

Is it possible to succeed with DIY CO2 in planted nano aquarium? In this nano aquarium which I set up 55 days ago, I used Elatine hydropiper as carpet plant. My only concern was “Can I be successful without pressurized CO2“ Now you can see the results and share with me: Did I succeed? I hope you enjoy this video where I wanted to show you that it is possible with good quality light, good quality soil, good fertilizer, and just DIY CO2. Where I get my plants: Light (LED): Onf Fla
