I 100% agree with riley. I have close to identical setup to your plant and its been running close to 3 months now. I only use fine gravel and root tabs and my swords are happy. You may wanna keep an eye on the 2x 23w (i'm assuming its the spiral fluorescent) light for overheating the tank. I find out early that I have to completely turn off my heater and open my windows to cool the room and my tank. Also my micro sword are doing ok. it just grew a little longer trying to get more light.
