Follow up to magnet scrubbers question

[fishetcinc]

Are the 220.56 and 220.57 safe to leave inside a reef tank while not in use? I mean, can they be left stuck on the glass and underwater indefinately?

Or will the magnets leach out any metals or glues? Or will the magnets rust or become damaged over time?

I am only used to using MagFloats which I do keep inside the tanks while not in use.

Thanks

I can assure you the magnets can stay submerged, damn mini lamptop keyboards, asnyway, it is built like a pump and sealed in PU resin.
