Aww but he's so gorgeous!
The main thing I would do is run the overflows through bulkheads in the BOTTOM of the planting box(es), instead of out the ends. And drill holes in the shelf under them, or whatever the box(es) rest on, to accommodate those. I also wouldn't use the lighting panel pieces ( ) to divide the compartments; they were too thin, the silicone didn't hold. They stay in place now because of strategically placed lava rock, but I'd find something a little thicker/more substantial to use if I was rebuilding them. Of course, I got a piece with broken corners for about $1 at Home Depot, so I'm not out much cash on that idea!The wife kind of approved the above the tank plant box. So you should totally mention some of the things you'd change. I'd be interested
