But, it's not accurate, and the single clicking? No single clicking. That's not a big deal. What's a big deal is the setting of the temperature which is the most important part. Oh the certified calibrated percise thermostat? Off by 5 degrees at all times. I have it set on 80, it shows 75. But my 3 thermostats I have on my tank including a digital one all show 85.

The red light is always on (not heating) and my guppies arnt giving birth. Can this be fixed? </h2> <div class="bvseo-question-detail"> </div> <div class="bvseo-author">Asked by: Burdy30</div> <div class="bvseo-answer" data-answerid="5286508"> What is your room temperature? If it is also 67 degrees then you need a new heater. If it is not, you need a new thermometer. Guppies are actually perfectly fine at temps down to around 62 degrees, they have a wide range of temperatures they do well in so if the tank is indeed 67 degrees, it is doubtful they care and they are doing fine. They can produce young for up to six months after one mating and may give birth when expected.
