Heaters FAQ
What size heater do I need?
A common rule of thumb is roughly 3 to 5 watts per US gallon, more in a cold room. Always check the wattage and tank size on the product label.
Can I leave the heater in the tank?
Only if it is rated as submersible. Follow the manufacturer instructions, and unplug the heater before water changes and cleaning.
Why does a steady temperature matter?
Sudden swings stress fish and can make them more prone to illness. A heater with a thermostat keeps conditions steady.
