Aquarium submersible heater

The aquarium heater is suitable for fresh water and seawater.
When the indicator light is on, it is working.
It works in any position horizontal or vertical to provide optimum aquarium water temperature.
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.
Do not install the chucks on the heating coils part.
Don’t clean the heater with detergent or similar things.
Before cleaning the aquarium or heating rod, please turn off the power for twenty minutes to cool off the heating rod, or you will be burned.
Please keep it away from children.
