Persistant Perspective
I have purchased a few floatswitches from floatwsitches.net (now aquahub.com) and have been very hapy with them in the past. I just got a bunch of there new switches (i-float) and found they have an exposed magnet inside of them. It is probably a ceramic magnet, but I still don't want to put this in a salt water tank. Anyone have any info on these thing?
