If you do aquarium maintenance in public places, you will eventually run into a situation where you will not want to cross a hallway with your aquarium vacuum hose causing a potential trip hazard.
One way to overcome this is to hang the hose over a metal door frame using your algae magnets. This will allow a clear path free from trip hazards as you vacuum and refill the tank. If a metal door frame isn’t available, look for another way to suspend the hose or revert to portable water change equipment.
