I have a couple islands that are supposed to "float" because they are attached by suction cups to the side of the tank...after a while, the suction cups lose their suck. I fixed them by putting styrofoam inside them, that way they can also float around the tank instead of having to stick to the walls.
Now all I need is the wrist strength to pull those useless suction cups out of the holes...
