test heater?

  • We are currently upgrading MFK. thanks! -neo
test the water temp, unless you mean without placing it in the tank then hmmmmmmmmmmmm. a test tank maybe?
 
Depending on the size of the heater, I generally use a 5 gallon bucket. for 200W and up I use a 55 gallon aquarium.
 
And a thermometer :)
 
Yeah, your just going to have to adjust the dial. If it continues to rise in temp, it is time to get a new heater. Jagers, are easy to use, and work very well.
