We've all seen these devices. They're the suction-cup clamps used to affix heaters, filter intakes, tubing, and other appliances inside the aquarium.
But the suction cups quickly deteriorate and no longer stick, the clamps loosen, and soon any torque on the appliances breaks things lose and leaves them hanging in the water. It makes the tank look like it always needs to be "put back together."
I have my tank set up pretty much the way I want it to stay. Is there a more robust solution to holding fixtures inside the tanks so they don't start deteriorating weeks after they are installed? Maybe something designed to be a bit more "semi-permanent." I'm thinking something hot-glued or somehow clamped or built into the framework of the tank itself.
