The Jellyfish Mood Lamp adds a relaxing, mood-enhancing touch to a room. That is, until air bubbles start to appear and kill the mood, causing the floating jellyfish to get stuck in a cluster at the top of tank. Fortunately you can get rid of these bubbles in a few simple steps.
Empty the tank, then refill it with distilled water. Be sure to use only distilled water, not tap water.
Add a few drops of washing-up liquid to the tank.
Mix water and washing-up liquid in a separate bowl. Soak the jellyfish in the solution.
Place the jellyfish upside down in the tank and they'll gradually sink to the bottom and start swimming. Wait a few hours. If more air bubbles appear, add a little more washing up liquid to the tank.
If you perform these steps during set up, you shouldn't have any problems.
It sometimes takes up to a day for the jellyfish to resume swimming properly.
If air bubbles re-appear just repeat the process.
