Good to know. Looks good from afar but you can see the algae at the front in the chips. On the plus side, if you do decide to remove it at least it is pretty big chunks and easier to totally remove than sand or small gravel.
Those are LED lights on there, right? They really do light up the tank very well. I think you have a good eye for aquascaping, as there is a good balance of open space and plants / caves, and it is very appealing to look at.
