I am in the beginning stages of adding live plants to a 2 year old 30 gal tank.It has worked very well

and now I'm ready to try something new.I have an under-gravel filter with a Fluval 204.Will this work with live plants?I'm not looking to go crazy at the start but I am a believer that If you are going to do something do it right the first time.If this adventure works I will be adding more But for now just beginning.Any help with this adventure would be most helpful.Thanks
