Intelligent Automatic Heating

The AQQA aquarium heater has a sleek design with an automatic constant temperature function! The external controller lets you choose between 59ºF or 93ºF. Simply hold down the Hold button until your desired setting shows up on the screen, then switch easily from Celsius to Fahrenheit by pressing this same button at the top right corner – it will restart heating when water reaches 1 ℉ (1° C) below set point.

If the power goes out during operation, there’s no need to worry because its memory retention saves all previous settings, which means good things happen next time around.

Digital LED Display

Safety Instructions

Position Correctly: Make sure that the heater is completely sunk into a body of water with no gaps; it should be horizontal or vertical and fixed in somewhere where there’s a better flow. And let the display lights be visible light as clearly possible!

Keep Water Circulation: Keep water in circulation in the tank when using the aquarium heater. The recirculating function will keep the tank evenly heated and prevent any localized overheating from happening!

Cooldown Before Maintenance: Take care when removing the heater from your aquarium so that you don’t scorch yourself with a hot surface and the heater coil is not burned out. Be sure the aquarium heater is turned off and allow at least 30 minutes for cooling before removing it from the water.

Do Not Put It In The Sand: Make sure to place your heater in a location that will not be covered with sand. This is because the particles of sand may cause it to stop working efficiently, leading to overheating, which could damage the heater! 

FAQs

Can the protective cover be removed to clean the heater?

The AQQA aquarium heater has a protective cover that can be removed for cleaning. However, please wait until the heating rod cools down completely before handling it to avoid getting burned by its hot surface!

Can this heater be used in an Acryllic tank?

IF IT IS PROPERLY SIZED, the AQQA aquarium heater can be used in any acrylic tank, but there must always be water circulation.

How do I change the temperature readout from Celsius to Fahrenheit?

The Celsius to Fahrenheit conversion is easy with this aquarium heater! In 500W and 800W models, you can press “+” and “-” buttons at the same time then hold it down for 5 seconds- in that time, you’ll have converted between Celsius and Fahrenheit.

For 100W, 200W, or 300W, press and hold the top button for 5 seconds to change your temperature display from Celsius to Fahrenheit and vice versa.

    • Hi Susan,
      Conversion between Fahrenheit and Celsius is easy. You may change the unit from Fahrenheit to Celsius by holding down the SET button on the top of the controller for five seconds. Then it will change the unit. Thanks.
