Nickle Plated Magnets

[jacksdad]

I am doing a skimmer mod for my NC24. Magnets are necessary to hold the assembly in place. they are very small, 3/16 diameter and .065 thick. My question is are they safe? I know glass scrubbers are magnets, but I want to make sure.
Thanks in advance,
Bob

I don't know how well nickel holds up in saltwater, but I wouldn't trust putting bare metal into saltwater for long-term. Plus, I know that nickel is often used in a copper-nickel alloy, and I would be afraid of copper contamination if this were the case of these magnets.
The magnets used for cleaning are incapsulated, typically in epoxy.

So if I cover them with a thin coating of epoxy I should be ok?

Also what about the magnets in powerheads. What type are they?

Ferrous oxide coated with epoxy.
Coat the magnets very well. Even a drop of saltwater will corrode magnets really quickly.
