Anyone ever attempt a tank of Cnidarians?

I would love to, just not in budget for a tank. I would love to figure a way to use a regular tank. Let us know if you go for it. I would be onboard to watch and learn.

I'm not up for a $2500 jelly tank either but even if I don 't do it I still want to understand the principles of flow that are in play.
I gather that for some reason a conventional overflow system isn't recommended but I'm not sure why. I have a 1 HP chiller so I can do that part.

jellyfish won't survive in a retangular/square environment. They just won't. Get either a kreisel or a cylindrical tank.
The flow has to be extremely slow, and maintenance is a beast.
You can not use an overflow because it has way too much flow, and they will get sucked into it and die.

Yes from what I have read is the flow has to be very light and no, NO suction in tank at all. They have no way to move, jellys just float in the current so they would end up trapped in a corner and or sucked down/into a overflow/siphon tube.

Kind of goes backwards from all that we have learn in our tanks - flow, flow and then more flow.
jellys are slow, slow. Read somewhere that the filter system on a jelly tank is multiple inlets and they alternate to keep the jellys suspended in the middle. I was thinking about putting two overflows on opposite ends of a semi circle tank and put the return from each in front of the overflows. Kind of like a counter current.

I had a buddy whose parents owned an acrylic shop. So he built his tank for cheap. What an awesome set up it was. He ended up selling it along with the jellyfish for triple what he payed for it.
