Aquarium submersible heater

Suitable for freshwater.
When the indicator light is on, it is working.
When the heating rod is working, it is recommended to install a water circulation system to achieve the best balance of the fish tank temperature.
The heating rod must be totally immersed in the water and no exposure is allowed.
Do not use the heating rod in the gravel to avoid affecting the temperature control effect.
Don’t clean the heater with detergent or similar things.
Before cleaning the aquarium or heating rod, please turn off the power for 15 to 20 minutes to cool off the heating rod, or you will be burned.
