defective frag racks in my tank

N52 "v2" MAG Rack - Oceans Wonders item# 205350
I bought these at brs and one elsewhere and after cleaning my tank and trying to find out why my corals where not happy I found that the magnets where all bubbled and corroded and rusted I have removed them and just want to alert you guys to check your magnets on any item and if not in use take them out like the glass cleaners luckily those have held up..post if yours are ok or not?
good luck

How old were the racks? I've got quite a few of those that are about 3 years old. As of yet they don't show any signs of failure. K&J Magnetics is a good source for quality sealed magnets if needed.
