Tips for Using FREESEA Aquarium Heater

Optimal Placement:

    • Strategic Positioning: Install the heater in an area with good water circulation, such as near a filter outlet. This helps in evenly distributing heat throughout the tank.
    • Vertical Submersion: Ensure the heater is vertically submerged to the appropriate water level as indicated in the instructions to function correctly.

Utilizing the External Controller:

    • Accessibility: Mount the external controller on the outside edge of the tank where it’s easily accessible for adjustments.
    • Temperature Settings: Experiment with different settings within the 63℉ to 94℉ range to find the optimal temperature for your specific aquatic species.

Safety Measures:

    • Regular Monitoring: Regularly check the LED display for real-time temperature and any error codes. This is crucial for early detection of any potential issues.
    • Auto Shut-off Feature: Familiarize yourself with the heater’s safety features. The auto shut-off function activates if the heater is exposed to air or if the water temperature exceeds 94°F.

During Maintenance:

    • Power Off Before Maintenance: Always unplug the heater before performing any tank maintenance or water changes. Allow it to cool down before handling.
    • Handle with Care: Even though the heater is durable, handle it carefully during cleaning or relocation to avoid damage.

Energy Efficiency:

    • Mindful Usage: Be conscious of the energy consumption, especially if operating near the higher end of the temperature range. The heater is designed to be efficient, but consistent high-temperature settings may increase energy use.

Acclimatizing Fish:

    • Gradual Temperature Changes: When introducing new fish or changing temperatures, do it gradually to avoid stressing the aquatic life.

Installation Check:

    • Secure Attachment: Use the provided suction cups to securely attach the heater to the aquarium wall. This prevents it from moving and ensures proper heating.

Dealing with Fluctuations:

    • Room Temperature Impact: Be aware that the ambient room temperature can affect the heater’s performance. In colder rooms, the heater might need to work harder to maintain the set temperature.

Warranty and Support:

    • Keep Documentation: Retain the purchase receipt and warranty information. In case of any issues, contact FREESEA’s customer support for assistance under the 12-month warranty period.
