Hey, so now that I have my tank functionally running, I'm looking for ways to make things run smoother...First of all, what do you use to keep cords and wires inside the fish tank out of your way with...will a pet store have suction cups or something of the like so my air tube won't be in the center of the tank? Is a gravel-vac supposed to siphon gravel, or do you just suck up water directly above the gravel to get the old food/fish dump up? And lastly, why do air pump boxes tell you to position the pump 1 ft. above the tank? Is this a rule you actually have to follow? Thanks for reading.
