Review on 🌿 Optimizing Aquarium Planted Tank with JARDLI Pollen Glass CO2 Diffuser by Tiffany Pine

I have a 1.65" diffuser but it took up too much space. I went with this 3/4" instead and have no regrets replacing it with a larger one. This is my first experience in the CO2 world and the local fish shop doesn't stock CO2 so I bought a 1.65 -" diffuser as it had a good view but I wasn't happy with the size. On the other hand it's just perfect for my 20g grow tank, produces tiny bubbles and I have it next to my canister filter outlet and CO2 gauge shows green with 3-4 bubbles per second.
