How to choose the Best aquarium heater controller ?
Types of Aquariums
The type of aquarium you own will help determine what heater you will need. For example, if you have a fish only freshwater community tank with most hardy fish, you can likely get by with a single heater and a relatively cheap one.
If you have larger predator fish like Cichlids or Arowanas, you will want a heater that can take a beating. This is where Titanium heaters can come into play as they are virtually indestructible.
For those of us who have sensitive inverts or exotic fish like you may have with a saltwater reef aquarium, accurate and reliable temperature is critical. A swing in temperature could cost us thousands of dollars in lost livestock with such setups. Therefore, as a reef tank owner, it is imperative that we build our heating system with multiple redundancies and safeguards to protect our livestock.
Power Or Wattage Rating
First and foremost, make sure it is rated for enough wattage to power your heaters or chillers. All heaters or chillers should come with wattage printed on the package or in the manual.
It is always best to have more capacity than you need rather than pushing the controller to the limit. For instance, if your temperature controller is rated for 800 watts its best not pair it to your 800-watt heater. It would be better to have something that is rated for 1000 or even 1200 watts in this instance.
Having a wattage buffer will prevent issues with power spikes and so on.
Control Unit Mounting
You’ll want to consider where you’re going to mount your controller before setting it up. To put it simply, mount the control unit away from humidity. One of the benefits of using an aquarium heater controller is that the thermostat isn’t located in the moisture and humidity of the aquarium. This makes it less prone to failure.
So make sure it isn’t mounted directly above or near the top of your aquarium. Place it somewhere away from your aquarium and mount it securely so it doesn’t get dropped.
As you see, a temperature controller is an essential fail safe for your aquarium. If you are still put off by the idea of purchasing yet another piece of equipment for your tank, consider this…Imagine how costly it will be to replace everything if your heater fails.
