Nero 3 "external" magnet water safe?

[Floyd-]

Simple question, can I place the external magnet in the back AIO sump area so my two Nero 3's are pointed to the front?

Yes

The back magnet of my hygger mini is inscribed with IPX67 which is really good. Even still I am not comfortable without a condom on it. Vacuum seal plastic or those small zip lock bag should be good.

I did this for my AIO, but to be safe I used a food shrink wrap machine to encase the back magnet. It can’t hurt to be too safe.

Awesome! thanks for the replies all.
I figured it should be safe but I cannot see any info about it on their site.
