Uuuugh sorry guys I’ve always struggled with those terms but yeah a temp gun sounds right.

I use it to monitor the temperature and turn on/off the heat lamp when it gets too hot. When I saw those could be used I was just like “OK YEAH I GOT THAT”

redshepard, in that forum, it mentions a thermometer you don’t use and a thermometer you do use?
from what I understand it needs to be one with a probe. So would I need one for each heat source plus the tank itself?

thermostats if I’m understanding correctly measure the temp using a thermometer, so do they cool/heat as well? I think I’m having trouble understanding how it works. I don’t think google explains it in depth enough.

Or can someone link me an in-depth forum JUST for thermo things?
