I am completely new to planted tanks, but I want my new 46G to be planted. I know there are Fluval systems for smaller tanks, but not larger tanks. I do not want to even mess with a DIY system. I just want to buy a system and keep up with it. The problem is, I'm not sure where to start looking. It's all very confusing for me. I will take any suggestions or links to a Co2 system I can buy that will work for a 46 G planted aquarium.
