You can cheat, you dont need a fully round tank a hexagonal or octagonal (or any of those) can work from what i read which means you just add plates into a tall tank (because u want it all the way around) the circulation has to litteraly be just that circulation, it has to push the water gently around the tank in a circle. The reason being that the jellys would get stuck in corners of a square tank and die as they dont have good means of self propultion. If your handy you can also use a heat gun to sofen acrylic sheets and let them roll around something that is large and round to create the perfect shape.
BUT at the same time its difficult to set up correctly and maintain, so if you are interested then good on you but do the research or you will fail.
