DIY Magnetic Frag Rock

[Mflores888]

Hello, I was wondering if anyone had some advice on how to do a magnetic frag rock to put on the back of a tank. I am looking for what magnets you use, glue/cement, or another way to make it stick. I've seen a couple finished projects but never the step by step process. If anyone has any input I would appreciate it.

Somebody suggested using the holders from broken jebao wavemakers and attach to egg crate.

What magnets does anyone use?

Neodymium are the ones to use, you will have to encapsulate them with epoxy or something similar fully though as salt water corrodes them
