those cheap glass thermometers may not be extremely "accurate", but they do
a much better job by and large than the stick on variety. Just bending the
stick on variety a little bit when attaching them can throw them way out of
wack. Plus the thicker the glass is the less accurate they are. Not saying
the stick ons are useless, but you have to be careful, which you are. I use
cheap ($6.99) coralife digital thermometers. They aren't exactly precise,
but better than any of the stick on ones I have found since aquarium
pharmicueticals stopped making the doc wellfish thermometers. they were the
only stick ons that I ever used that were extremely accurate, even on large
tanks.
