Thank you. A few more questions if you dont mind. Is CO2 necessary for these plants or is liquid plant food fine (API CO2 booster). Or is there something else that you might want to suggest so I can have a lush tank with my fish. Right now I currently have a T8 65k bulb running the length of the tank on the bottom shooting in from the side so my hairgrass can have tons of light. I want this stuff to carpet and really take off.
