Most of the el cheapo aquarium thermometers have so much variance that I find myself wondering what the temperature actually is in the tank. For example on my two 10g apisto tanks I have a cheap glass and a digital that are in opposite corners of each tank and the temperature variance is like ~3 degrees F from the highest to the lowest.
If spawning is tied so closely to swings in temperature, how do all of you ensure that you're getting the temperature that you want in your tanks?
