Tips for Selecting and Using Aquarium Heaters:

A minimum of 3-5 watts per gallon is recommended in keeping your aquarium at optimal temperature level. The use of multiple heaters in larger aquariums can allow even heat distribution.

The heater should always operate under water.

Please cut off the power and wait for at least 10 minutes before changing water, touching the heater or taking the heater out of water.

Please don't use in the water if the wire or glass tube was damaged
