I am designing a vacuum suspended fish tank. But I don't know enough to understand whether the design on the right would work as well as the design on the left.
I don't want a big open area of water, I want a few inches at the bottom for aeration and access to the pump and plant roots.
It am looking at a larger volume, about 75 gal/280 liters.
I know people have used vacuums to do crazy things, such as to have many thousands of gallons with little portholes to pet the fish.
