Jelly-Guard – Back Plate Cover (Nano)
The new Jelly-Guard is a durable back plastic guard that attaches to your Jelly Cylinder Nano ® via suction cups. The Jelly-Guard is designed to cover the back plate of the aquarium and prevent weak or compromised jellies from getting stuck.
Note: Jellyfish should never be getting stuck on your aquarium’s back plate. If this is happening, it means something is affecting the animals negatively, to where they are too weak to get off the back. The Jelly-Guard will prevent sticking but ultimately the real underlying issue should be identified and addressed. We suggest checking your Ammonia, Nitrite, and Nitrate levels. Ammonia and Nitrite should be zero and Nitrate should be less than 20PPM. In some cases, suctioning onto the back plate can be caused by excess light or poor water flow.

I’ve had my Jelly Cylinder Nano for over a month and the Jelly-Guard has been a game-changer. My jellies no longer stick to the back plate, which was a constant issue before. The suction cups hold firmly and the cover is easy to install. I still check my water parameters regularly, but this has made maintenance much easier.

The cover fits perfectly and stays in place even during water changes. I noticed my jellies moving more freely now. It’s a simple solution to a common problem, and I appreciate the clear design that doesn’t block visibility.

After installing the Jelly-Guard, I haven’t seen any jellies stuck on the back plate. It’s a small but effective addition. The material feels sturdy and the suction is reliable. I recommend it to anyone with a Jelly Cylinder Nano.
