OK, I am sure this sounds stupid but it is driving me crazy.  I cannot get my darn themometer to stick to the side of my tank anymore.  Since october there have been no problems and then all the sudden for the past few weeks the thermometer goes awol and I find it bobbing underneath my filter return.  It will stick to the glass for half an hour or so and then bam, its off to the races.  Do any of you guys know any good techniques to make it stick?  Should I just silicon it in place? Or should I just shell out the extra two bucks for a new one?
