Question: Where Should I put My Aquairum Heater?
Answer: I'm glad you asked, as this is a simple, but often overlooked question. The best location to place a heater is near the water flow, such as the outlet (or inlet) from the filter, or in the stream of a power head. Why? Because having water flowing directly past the heater more quickly and evenly disperses heated water throughout the tank.
If you have a tank that is over 40 gallons, consider having two heaters placed at opposite ends of the tank. The water temperature will be more uniform throughout the tank, and in the event one heater fails the tank will not be completely without heat.
