View Full Version : K&J plastic coated magnets. Your thoughts...

I've been reading up, and for the most part it seem people like these magnets.


I've recently purchased these to hang frag rocks on the back of my tank. They hold well but I did notice one of them developing a "red ring" in the center of the mag after only a couple of days... surely this isn't rust? Or could it be? Seems strange considering it was only in the water a few days... It is in a high flow area near my overflow... could it be other debris?

What are your experiences? Can I trust these mags in my reef tank long term?
