Do those magnafloat things rust after a while? I got on from someone used it and it looks like it leaked some orange ish red colored stuff in the water. I had some redish algae on the glass but this looked more orange. One of the soft corals (colt maybe) that was under it when it happened looks like its wilting and discolored. I thought it was my old one and didn't wash it but now I'm thinking it was the other persons.
Thanks
