Magnets bad for saltwater

[Pizzapro83]

I am using magnets to hold my float for ATO . Is there any concerns I should be worried about with the magnets in the water

 

[killingseed2000]

by what i have read , yes bad and should be covered in some way.

 

[Pizzapro83]

What do you think I can cover it with

 

[Poseidon]

I would paint them well with 1 hour epoxy, let dry overnight at least.

 

[Pizzapro83]

What kind do you think

 

[Poseidon]

Go to a hobby shop, the RC airplane section, and get some 2 part epoxy that you mix. The longer the set time, the stronger the glue. Epoxy ranges from 5 minute to 24 hours, a 1 hour mix should be plenty. Make sure to let it cure overnight.

It really depends on what type of magnets.
If they are ceramic magnets they are usually considered reef safe.
I've been using the 2"x1"x1/2" ceramic magnets in my tanks for years with no apparent harm.
Do you know what yours are?

earth magnets

 

[mfinn]

Rare earth magnets aka, neodymium magnets are sometimes coated and from what I've read the coating is made up of nickel and copper ,

Plasti-Dip is safe in SW and makes a good coating for magnets.
