I have a thermal imaging thermometer in my shop. I should try that on my tank and see how its temp compares to the Apex.

In the winter my tank runs between 77 (night) to around 80/81 (daytime).
In the summer it runs around 79 (night) to 83 (daytime). I don't do the temperature shifting on purpose. Mother nature does that for me :neutral:

why? Because my tank likes it? :noidea:

In my experience the blue light messes them up.

I run my tank right around 80 at the moment and everything seem to be going well.

I use traceable thermometers as well to calibrate everything. We use these in our lab on a daily basis so we have about 6 boxes of these things on hand at all times because some people tend to spill some nasty stuff on the plastic. These are the 0.2 degree accurate thermometers from Fisher Scientific. The cost we get them at works out to be quite a bit less when you buy 10 boxes.

When I set up my apex. I used 3-4 different thermometers and averaged them :). Who knows how close it is! $40 isn't bad but I would be tempted to get the .2 accuracy one. Do they really have to be calibrated yearly?

Each thermometer comes with a little sticker when they're due for calibration. I think our newer stuff is due July 2018, but from my experience they don't fall too far out of calibration that quickly that it would be absolutely necessary, there are always ways to see roughly how good your calibration is.

The thermometer you linked is +- 1.5 degrees. Though the description mentioned an Ultra model that is 0.4.

If you or anyone for that matter really wanted one, I don't mind getting some from the lab manager at cost and sending them, she's generally quite easy about that stuff as long as it gets paid somehow. I think they run 40-50 (can't recall) at our cost and I don't assume it would be too awful to ship something so light. For some reason BRS sells them at 99 each, but I guess they don't assume they'll be selling them in large volumes.
