YukiHalu Adjustable Submersible Aquarium Heater for 5-60 Gallon Tanks

The YukiHalu 25W aquarium heater is designed for 1-5 gallon mini fish tanks. With its compact design, it takes up minimal space in the fish tank and is easy to hide. Featuring an automatic constant temperature with 1°F (0.5°C) accuracy, this heater can precisely adjust the water temperature from 64 to 93°F (18 to 34°C). Suitable for both saltwater and freshwater aquariums, it operates on a rated voltage of 100-130V.

The heater's advanced Intelligent Frequency Conversion Technology ensures consistent water temperature. By automatically adjusting the working frequency based on temperature variations, the heating is stopped when the set temperature is reached. This innovative approach can reduce your electricity bill by up to 49% compared to traditional heaters.

For your fish's safety, the heater is equipped with overheating protection and out-of-water protection. If the heater is out of the water or the water temperature exceeds 95°F (35°C), the power will be cut off, and heating will stop automatically. Error codes 'E1' and 'H1' will be displayed to indicate the respective issues. The heater will resume operation once the problem is resolved.

Convenience is a key feature of this heater. The external temperature controller allows you to easily set the desired temperature without getting your hands wet or contaminating the tank. The large digital LED display makes it simple to read the current water temperature, and the intelligent indicator lights (green for no heating, red for heating) provide real-time status updates.

The heater's built-in dual temperature sensors ensure accurate water temperature monitoring, eliminating the need for a separate aquarium thermometer. Additionally, the heater will remember the temperature setting, so you don't have to reset it after a power outage.

Regular maintenance is essential for the heater's optimal performance. The suction cups must be cleaned monthly to prevent the heater from falling off and breaking due to weakened suction caused by stains. Before installation, it's crucial to inspect the glass tube; if it is cracked (but not completely broken), do not use the heater.

The size chart provides guidance on selecting the appropriate heater based on your aquarium volume: 25W for 1-5 gallons, 50W for 3-10 gallons, 100W for 8-20 gallons, and 200W for 15-40 gallons. Remember to fully submerge the heater in the water and position it in the water flow, avoiding any burying or obstructions.

In summary, the YukiHalu 25W aquarium heater offers a compact, energy-efficient, and user-friendly solution for your mini fish tank. With its automatic constant temperature control, advanced protection features, and convenient external controller, this heater ensures a stable and safe environment for your aquatic companions.
