I put in the blue gravel in lieu of the white sand I used to have in it. The sand got really dirty and disgusting. I just did the changeout a week ago. And I have fluourite underneath the gravel for the plants.

Thanks for the compliments. This is my first big tank so it's a lot of trial and error for me. I'm sure it will continually evolve and maybe one day I'll have it completely dialed in.
