Designed specifically for jellyfish, the mid-size Pulse 80 tank has a volume of approximately 23 gallons—enough space for 10 medium jellies and it’s made of crystal clear 100% cast acrylic. A smaller round tank as well as a larger 46 gallon version is also available. To make the display dramatic, there is built-in color changing LED lighting. Mechanical & biological filtration is also built-in making the tanks a complete, simple to maintain system.
