| || | My lighting is around the 6500K except in the smaller tank it's higher, I can't remember what, but I think in the 8000K. I regret in the smaller tank I didn't put the plants you see in the foreground (hygrophilia angustifolia) in the background, but they are so rooted, I can't move them (I've tried). I'm going to use up the fertilzer I have and than buy the comprehensive flourish I hear so much about here. I'm using the "Plant pack" by Seachem. I also have these substrate "sticks" in the tank with the sand.

Another factor is the k rating of your bulbs - plants need something around 6500k to grow best, again taking up more of the ammonia
My heavily planted tank normally runs at around 10-20ppm nitrate but is a little over stocked
I've spent enough on plants for now, so I'm holding off on these growing (or not). I had some supposed low light plant (bushy, can't remember name, they called it a "fry saver") but it died almost immediately after I planted it)
