1. Adjust the current intensity: If the current is too strong and jellyfish are attracted, you can try to reduce the power of the filter or pump to reduce the impact of the current. This can improve the situation of jellyfish being sucked.
2. Modify the design of jellyfish tube: If the design of the sample inlet or filter outlet of jellyfish tube is unreasonable, consider modifying the structure of jellyfish tube. By changing the position or angle of water inlet, or adjusting the position of filter and the shape of water outlet, the influence of water flow on jellyfish can be reduced.
3. Provide a suitable environment: jellyfish need suitable water temperature, water quality and nutrients. Ensure that the water temperature is appropriate, the water quality is clear and transparent, and the salinity of water can be maintained with appropriate sea salt. In addition, attention should be paid to providing enough light and proper feed to keep jellyfish healthy.
If none of the above methods can solve the problem, it is recommended to consult aquaculture professionals or seek the help of local pet shops, who can give more specific suggestions and solutions according to the actual situation.
