I know that adding CO2 changes the pH. I also know that you need more light and that you need to add nutrients if using CO2. I also know that these reasons contribute to making a CO2 setup one that needs lots of time. These are reasons why I don't want to use CO2 permanently. What I want to know: What will happen if I use a DIY CO2 installation for the 1st month only after setting up my aquarium? will the planbts grow quickly and what will happen when I cease using CO2 after the initial month? thanks.
