i'll be buying a lot of these and see if they have enough strength to hold up a power head or something.

im planning to isolate them by gluing 1/8" thick acrylic sheets around it like a sandwich.

 

wat do you guys think?

I seem to recall reading that the force of the magnet decreases as the cube of it's thickness. So depending upon their strength you might find that the 1/8" acrylic + tank walls will drop the force a little too much to hold up a pump... of course I couldn't see a strength rating on that site so it may be irrelevant.

get teh epoxy coated ones.... therefore you don't have to sandwich anything and they are waterproofed.
