Hi! I am looking for a recommendation on reef safe submersible magnets. I currently have half a dozen mag rack pros and Id like to wall mount a few of them, unfortunately the included bracket is not submersible from what I understand, Id also be sticking it in front of a few sump chambers so the design of the included magnet doesn't work for me without modification. Im looking for an answer from someone who has used a submersible magnet long term ( lets say a year) without seeing rusting or leaching or anything out of the ordinary coming up on an ATI test. Thank you !
