About this product
The box holds the Zoo Med aquarium heater, one suction cup and a digital thermometer display. This 100 watt model is made for aquariums up to 30 gallons, and a preset setting holds the water at a top of 78 degrees Fahrenheit (26 degrees Celsius). Aquatic turtles such as Red-eared Sliders, African Sidenecks, Musk and Painted turtles can use it, and it suits fish tanks as well.
What comes in the box
- The 100 watt heater itself, sized for tanks up to 30 gallons.
- A suction cup for attaching the heater to the tank wall.
- A digital thermometer display that shows the water temperature.
Submersible glass housing with a digital readout
The heater goes fully underwater, and its digital thermometer display lets you read the water temperature without a separate gauge. A suction cup holds the unit in place on the inside of the aquarium.
The housing is black. Because the heater is submersible, it sits below the waterline rather than hanging over the rim.
100 watts for tanks up to 30 gallons
The 100 watt rating matches the stated tank limit of 30 gallons. The heater is preset, so there is no dial to adjust: it warms the water to the top temperature given above. An automatic shut-off cuts the unit when it is lifted out of the water.
Checks before you buy
Measure your aquarium first. A tank larger than 30 gallons is beyond the stated limit for this 100 watt heater, so a bigger volume needs more wattage.
The turtle list covers Red-eared Sliders, African Sidenecks, and Musk and Painted turtles along with other aquatic turtles. If yours is a different species, confirm the heater suits it before purchase.
If your animals need water warmer than the preset top temperature, this model does not reach it.
