Hello everyone- I am trying to create a little frag rack within my display and have an idea to connect a magnet on the inside of the tank and then obviously 1 outside to hold the rack in place. My question is, is there any coatings or finishes on magnets that I should be aware of that are not water safe? For example I'm looking at magnets on Amazon and some are nickle plated and made of Neodymium. I don't want to buy a algae scraper magnet because they are pretty expensive. I have tried to look at home for other fish stuff to make this out of but nothing seems to be strong enough to hold the rack I want.
So does anyone have any recommendations. I was thinking of something like this...
