I've had my tank running successfully for the last year and decided to change it a bit. I've just changed the layout of my 3ft tank and bought a range of new plants, however there were only tags on two of them to identify them. I've looked at a few websites in an attempt to identify them but no joy. Also I added extra gravel on top of the old substrate as the gravel sand mix I've had for the past year was really too thin to properly support plants. Does this mean that I will have to start the cycling process over again, especially since I did a 100% water change? I am still using the old filter media and the old substrate is below the new gravel. Pics below:

I haven't identified the 3 large plants in this picture although I believe the middle one to be an amazon sword?
I have no idea what the middle plant in this picture is
The plant in the yellow box also needs to be identified but it can be hard to make out
cheers
