FAQs For Underwater Heater for Turtles
What size heater do I need for my tank?
The heater’s wattage needs to be matched to your tank’s gallon capacity. As a general guideline, a 50-watt heater can heat a 10-20 gallon tank, 100 watts for 20-30 gallons, 200 watts for 30-55 gallons, and so on.
How do I set the right temperature for my turtle?
Most turtles do best with a water temperature in the 75-85°F range. However, the ideal temperature can vary by species, so research your turtle’s specific needs.
Where should I place the heater in the tank?
Placing the heater near the filter outflow helps circulate the heated water. Avoid putting it too close to objects or decorations that could impede water flow and heat distribution.
How often do underwater heaters need to be replaced?
With proper care and maintenance, most quality underwater heaters should last 2-4 years. Replace heaters sooner if they begin to falter or any part appears damaged.
Can I leave the heater on when the tank is empty?
No, never run a tank heater without water. They are designed to be fully submerged. Running them dry can severely damage the unit and poses a fire hazard.
