Something May Be Wrong With My Heater

[Gazoo]

...i use the visitherm heaters in all my tanks as i find them to be a good reliable heater but the temp setting is only a guidline to get an acurate reading...

In two of my three visitherm heaters I need to have the setting 4-5°F higher than the actual temperature. This is no big deal since they keep a steady temperature at the adjusted number. The only way I know the actual temp is because of a thermometer.

If the thermostat on your heaters fail you will only notice when you feel the water and you wont know the exact temperature. Testing the temperature with your hands isn't a good idea as your hands could be cold making the water feel even warmer.

The thermostats on heaters are never 100% accurate.

By using a thermometer you can view how warm the water actually is. I bought one from ebay for around $2. It sticks onto the inside of the tank with a sucker.
