I'd like to eventually tie all my tanks together to a single filtration system, but in order to do this I'd need to drill my tanks. This can be tricky and nearly impossible if the glass is tempered, but I think I've figured out a way to make the tanks "drilled" without actually having to cut the tank.
It works on the principle of siphoning keeping the water level equal in two different containers. If you run a tube between two tanks and fill the tube with water, then as you remove water from one tank it will suck water from the next until they both have lost the same amount of water.
If you drill a hole in one of the tanks then it will not only drain water from the tank with a hole in it, but it will also drain an equal amount from the other tank connected by the siphon hose.
If you then pump the water that's being drained from one tank back into the second one then you've got a complete cycle.
Below is an illustration of what this would look like. I'd build an overflow box on the inside of the tank. The top of this box would be at the desired water level. I'd then build a small box on the outside of the tank with a hole in the bottom for the water to drain. Connect these two boxes by a siphon (tube) and you're done. As the water drains out of the exterior box it will suck water from the inner box. The water that drains out is pumped through filtration and back into the tank. As the water level in the tank rises it flows over the top of the inner box and through the siphon tube back into the external box.
