How to Design a Jellyfish Aquarium

Two Methods:Flow Bar MethodPseudokreisel Method

If you're not using a tank and filter setup that's specifically designed for jellyfish, you'll need to make modifications to make sure your beautiful jellyfish don't turn into soup. The main objective is to keep the water circulating so that the jellyfish stay in the middle and away from the filter.

Method 1
Flow Bar Method

    Make the screen.
    • Option 1: Use a sheet of semi-rigid plastic with regularly spaced holes (4 to 5 mm diameter) drilled about an inch apart. Make sure to smooth out the holes.
    • Option 2: Use nylon window screen that is attached with aquarium-safe silicone sealant to a plastic frame.
