I did a quick search and couldn’t find much. I’m looking at the Hygger Mini Wavemakers for a future AIO build. Looking at Amazon review pics, it appears some have them attached to the back wall with the external magnet submerged. Can anyone confirm it’s a sealed magnet? I asked Hygger but haven’t heard back and the Amazon ad only states the controller is not submersible. If it’s not sealed that’s fine, I have some options. Just trying to plan ahead.
