In relation to my other post (too lazy to link lol) what type of thermostats do you use for your tanks (if you even use thermostats) There are tons of different types and I want to see which ones are popular. My budget is around 40$, but I will probably end up spending more on one. P.S. I saw this really awesome thermostat that allows you to set how many degrees the set temp will go down at night. The thermostat was yellow, and a thing lights up orange when the heat is being regulated. I would love help on deciding, love you all!
