ERAARK support FAQ

Common questions about manuals, registration, and support for this brand.

  • What app do I need to control my ERAARK smart fish tank?

    ERAARK smart aquariums and heaters are designed to operate using the PETKIT app. You can download the PETKIT app from the iOS App Store or Google Play Store to connect and control your aquarium's lighting, water pump, and temperature settings.

  • How do I clean the filter media in my ERAARK aquarium?

    To properly clean the rear filter chamber, first disconnect the power supply. Remove the filter elements and gently rinse the filter cotton and biochemical media using tank water. Never use untreated tap water on the biological filter media, as this will destroy beneficial bacteria.

  • How often should I change the water in my ERAARK fish tank?

    To maintain stable water parameters, it is recommended to replace no more than 1/3 of the tank water weekly using a dedicated water-changing tool. Always treat tap water to remove chlorine before adding it to the tank.

  • Why does the water pump stop running when I open the ERAARK tank lid?

    This is part of the built-in 'Feeding Mode.' When the feeding lid is opened, the water pump automatically pauses for 10 minutes to prevent fish food from being immediately sucked into the filtration system. You can enable or disable this feature in the app.

  • How do I connect the ERAARK Smart Aquarium Heater to Wi-Fi?

    Double-click the power button on the heater's control module to activate Wi-Fi networking functionality. Then, open the PETKIT app, press the '+' button on the main page to add a device, and follow the in-app prompts to pair the heater.
