Hey guys. I've been look at a Fluval CO2 system for my forty gallon tank. I have three amazon swords in it. I have a 6500k light at 8hrs a day and miracle grow soil. I have been told I do and don't need to CO2 to keep plants alive. I found the Fluval system online for about $60 an figured for the price it couldn't hurt. Just want to know if it's worth it or not.. Also if you have any recommendations of systems.
