I finally want to try a high tech planted tank, I want to make this as cheap as possible so I’ll be using a 2 gallon so almost any light will be sufficient. But I’m wondering how I can setup a co2 system for cheap($50>) that’ll last for a good amount of time. I found these cartridges on Amazon and wondering if these would work, but how would I set it up, would I need a regulator, bubble counter, or just a diffuser setup straight to the cartridge? But how would I connect the air tube to the cartridge?
