Choosing Your Heater

Ideal reef temperatures should be between 74-78F.

A heater is probably the most likely piece of equipment that can break in your tank, so always keep a backup handy. Heaters range from less than $20.00 to over $200.00. Mostly, the difference is in construction materials, and if the heater is digital. Digital heaters are used by many people because they generally have a little screen to see the temperature to the tenth’s decimal place. They have heaters with controllers as well, that are very accurate (JBJ comes to mind). They make submersible heaters as well, which I recommend. I run two heaters at all times, in addition to a backup heater I have in my sump that it set to turn on if the tank temperature drops. Again, make sure you always have a backup handy.
