Do magnets damage reefing equipment in my sump?

[mishmaster]

Will strong magnets, like the ones used to hold up a frag racks and other equipment, damage sensitive electrical equipment kept in you tank stand like Apex controllers, ph probes, temp probes, DI resin, if they are placed next to each other?

These are the magnets I am using in my sump where I keep all the equipment and reef supplies?

You will probably be fine. I've stuck huge magnets onto hard drives for several minutes and the hard drives still functioned and was able to pull data off them.
