My old 50 gallon tank is starting to show it's age. There are a ton of scratches that that have appeared. The silicone in the corners is starting to show some issues that I'm getting a little nervous about. I built the tank myself almost 10 years ago. So I got in touch with my favorite tank...
Had to upgrade my Nero 3 to use Ocpondpoachers nem guard. His design works very well. Plus the ABS color fluoresces under blue lights and the orange glasses.
