I have recently bought a couple of cheap max-min thermometers from a
local store. I put them next to my old thermometer for a weekend. All
3 were close (+/-1degree C) on the min temperature, but differed by 10
degrees C on the max. Now I don't know which if any of them to believe.
I suppose I can check the lower end of the temperature
range by putting them in the fridge or ice/water, but does anyone
know of an easy way of checking them in the range 20-30 degrees C?
I've recently moved a tank into my office, in the belief that it
would get plenty of light. Well it seems I was wrong, and although I
was getting sun a few weeks ago now that its mid summer here
I'm getting little direct light. Is there any way to measure how
much total light a tank gets over a day, and compare
that with an "ideal" amount of light? Or should I just assume the more
light the better and put a fluorescent of some sort on the tank?
Thanks for any ideas/comments
