When you are keeping a colony of Jellyfish Polyps, use a small tank. The food is more concentrated and the water changes are smaller. I recently set up a 2.5 gallon aquarium for my polyps. The water flow is too fast to allow the ephyra to not get sucked into the filter, but now I'm just trying to expand my polyp colony.
What I have is a 2.5 gallon tank, a whisper 10i (internal filter), and a large heater with my polyp colony on it.

I will try to add a piece of rock to the tank and make sure it has no hydroids. I think it will be much easier for the polyps to stay attached to some rock than glass. The rock will also provide biological filtration.
