The canopy just sets on top, you wouldn't have to use it. Previously I used hand-made HOB overflows, but now I have a glass holes 1500 GPH to go with it. I haven't drilled it yet, as I figured the new owner might want it fully intact for some reason. The stand and glass are about 1.5 years old. Glass is great except for one scratch on the back panel in this picture. Once lights are on its very hard to see, and it's small enough that I can't feel it with my fingernail.
