Sorry man maybe in here people believe you need co2. I would have to start a new post because i would have to add a bunch of pictures to show the difference between my high a low tech setups. Same plants just way better results. Results sell themselves not people pushing to sell a products. None of those IAPLC guys use low tech why because they dont get the same results. Their are plenty of groups out there for low tech plants and no one believes that you need to use co2 to get results man. Dont believe me go check out low tech planted tanks on facebook 36k people in there believe the same as me... I am not arguing that you need co2 but co2 gets better results.... Its just silly to try to argue against that, maybe in here you can get away with that because these are your peeps but the rest of the world don't agree with you.
