Here are some pictures of the green sand. Excuse the mess, but this was right after I set it up and I was trying to get my Ps to eat and before I put my other filters on it. I will take some more recent pics with my webcam.
These are the best pics I could find of the blue sand. These pictures are old as well. As you can see this is back when I was having an algae problem. Plecos get a bad rep on here, but the one I put in this tank worked wonders. I got sad looking at these pics, I miss my ray. I should have never sold him. Maybe I will get another one day. I don't think the camera did the sand justice. The blue is beautiful.
These are videos I took a few days ago. I originally took them to show the fish, but I figured I could post them on here to give everyone a better feel of how the sand looks.
I have a background already for the 125g, the one with the blue sand. It has ruins on it that match the decor of the tank and has a base color of blue.
