You know they need a special type of tank right?

They require a very specialized tank that's typically round and uses a very gentle pump system to keep them from bouncing off the tank wall. They can be kept, but lots of work and skills required.

There is a local bar that has "Mermaid Lounge" cheesy but it's vegas. They have a huge jellyfish tank, you can see them in the pic at the top.

Well, undergravel filters have hardly any flow if you set them up right. There are so many ways of using them. I would personally use a deep sand bed with them and either a powerhead with reverse flow or airstones shoved down at the bottom of the tubes.
Or one of those cheap clear internal corner canister filters that you can add whatever media to them and an air pump to run it. The guy in my town who runs the only lfs, (only freshwater fish), has used this system in all of his 30 tanks for over 46 years. Just some ideas of low-flow filtration.

Actually I have a membership with the Newport Aquarium in Newport, KY. They have a jellyfish room which is very sweet. They are very thin tanks in the walls and don't appear to be rounded, but I actually was looking at perhaps a hexagon tank to sit in the corner of my dining room. It appeared that they needed a lot of up/down room and less side to side. I had no idea how many I could keep in one tank and still allow them to be happy. I think it would be a good idea for me to contact Newport and see if perhaps they could offer some advice. I wonder if someone has an actual tank setup somewhere in terms of some diagrams?

I just checked jelliquarium, and that's what I need! A bit pricey, as the $1,500 tank is aweful small, but I think I can build something similar. They at least have some jellyfish for sale at reasonable prices, so I'll find out how durable those moon jellies are and see about building something.
Thanks for the help!

LFS for some crazy reason got a couple of jellies in. It was sad. They kept getting stuck to the pre-filter on the intakes and try as she could to keep them off, they both died.
Stay away from Box Jellies! Saw a special on them on the National Geographic Channel. They are killers!!! WHEW!
If you go for it, I hope you will post a "As I build it" thread.
BEST WISHES with it!

I'm still up in the air about it to be honest. From what I've read, some are just nigh impossible to keep due to feeding and lighting, since some are still photosynthetic. The cost is what is getting me. I need to be able to get a round tank, perhaps with an overflow, but the returns would need to be something like pvc pipe near the bottom of the tank, leaving the center areas mostly undisturbed. I wish Newport Aquarium had guides 
Plus, it seems as if the jellies may need 55-65 degree water, so I have to work a chiller in there as well. Since the stuff can't be in the tank, I'll need plenty of room to fit this stuff into the sump.
The crappy part is that if it doesn't work to keep these things alive, I have no more use for it.
I wonder if a 46G bowfront would possibly work for these animals?

They are not impossible to keep BUT you DO need the right tank, and that is not a regular hobbyist tank! Not a hex, not a bowfront, not something with sand. People don't understand how delicate these are. No undergravel filter, no corners, not even quite the same overflows.....none of these are appropriate for pelagic jellyfish (those that swim around).
You need a Kreisel tank, and there really is no way around it. If you have the proper tank, with a chiller, they are not hard to keep. But please don't do this if you are not willing to make the investment in a Kreisel. You don't necessarily need to spend 1500$, I am sure you can do one DIY, but it is not cheap either.
If it doesn't work, the tanks can be used for seahorses as well, without much trouble, IMO. But they are a challenge to clean tanks, often the siphon is nothing larger than airline tubing and even then, you can damage them.
