Strong Magnets for elevating Marco Rocks

[kaijor]

Hello,

I have a few frags that I want to elevate in my reef tank. I have them attached to some Marco Rock for now. I'm thinking of gluing magnets to the Marco rock and attach it to the glass. Has anybody used these magnets before? If so, how strong are they?

Thanks!

The tank I saw setup with floating marco rocks used the waterproof Tunze magnets.
