Two Little Fishies Nano mag cleaner…. Safe?

[HALFFISH]

I’ve been keeping a Two Little Fishies nano mag in my tank for about 3 months now, I’ve heard horror stories of these cleaners rusting inside of the tank over time… I was wondering if anybody has had any experience with this? Do you keep your magnets inside the tank 24/7? Or do you take it out every time after cleaning?

I've heard others recommend to take the magnets out which is a good idea especially if you are concerned. That said, mine stay in my tanks.

They rust. Every single one i've owned has rusted.
