My Tahitian Moon Sand Is Magnetic

[onidrase]

Hey guys, a few months back I made a move on changing from playsand to a thinnish layer of black tahitian moonsand by Caribsea Super Naturals, and with a mishap of me dropping my nametag into the tank (my tag is a magnet with a metal back as opposed to a pin) I realized this sand is pretty highly magnetic. While the fish don't seem bothered by it right now, magnetic things in my fish tank are pretty worrying. The bag says this stuff is pH neutral and all, but I'm full aware that some companies aren't the most trust-able in their products.

What exactly is this sand? Will it cause harm to my fish in the future? What do I do?

I don't see it causing any harm, all living creatures live in tune with magnetic fields surrounding Earth. Though it might cause problems for migrating animals who use the magnetic fields to find their way, I doubt your fish are planning a nice summer migration to the Amazon
It shouldn't cause problems, its not like the sand is a huge electromagnetic like the ones in MRI machines

The sand probably also contains either iron or iron shavings to make it black without affecting chemistry of the water like with dyes.
