Looking to add some shelving to outside panel of my IM APS stand to hold some equipment and get it off the floor next to the tank. Is it easiest to use some plastic L-shaped shelving and attach it with a bunch of velcro? Really difficult to mount anything to these metal stands. Tried to velcro the powerbrick of one of the LED light bars to the side of the tank but the glue itself gets weak with the heat and falls off.
