Hello Elizabeth,
Those jelly tanks that are shown in the article link you sent are no longer being sold by Reef Eden. They actually stopped distributing the other tank after repeated issues with them and re-designed their own from scratch with more advanced filtration. The new jelly tanks are amazing and you can see them at the link below. We had one displayed at MACNA in Denver a week ago and people were really ooohing and awwwing about it.
Let me know if you're interested in one of the Aurelia tanks or if you have any questions.
Thank you,
Lindsey
