Hi Sandra. There must be a confusion. They are absolutely not the same magnets. The initial algae scrubber magnet that comes with the Shrimp Bubble Ecosystem is a ceramic magnet that has a pull force up to 0.5 lb. The Power magnet is a NdFeB, Grade N42 Magnet, plated with: Ni-Cu-Ni and coated in Plastic, so it will never rust. The Power Magnet has a Pull Force of 3.45 lbs when placed against a metal plate, (in your case, against the exterior handling magnet) which is very powerful for such a small size magnet. ALL customers who tried this magnet noticed the big power difference between the ceramic one and the Power Magnet. Please don't let the small size of the Power Magnet deceive you. We know that you will notice the difference from the moment you try working with it. PS. Can you please post a picture with the Power Magnet set you received from us? Thank you.
