Can you safely silicon a swelling magnet?

[Invictus]

My ATO magnet seems to be swelling after only a couple of months in water. Could I try coating the magnet myself with some spare silicon, or should I just purchase a magnet?

If the latter, any suggestions for smaller reef-safe coated magnets would be appreciated.

Only after a few months was the ato new or in storage for a while? Not good if a new ato or if it's a house brand...
