The laws of physics are on your side when you expand a fish tank. Raising water from one water level to another creating multiple water levels is possible using a closed capsule sealed below the first water level. Going in from inside with the float, see video of how this works HERE. Here are two tanks side by side with the same or very close water levels. While you remove air from the top tank you will need to add water to one or both tanks, until the water is above the center gap, your water level in the bottom tanks will not be the same.
