Stable Temperature: Water temp may vary with volume and room temp. Lower settings or reduce water for faster cooling. Please Read details before purchase to ensure it meets your needs (Size, Voltage, Power, Tank Capacity, Cooling Range, Usage). Friendly Note: The cooler's performance depends on water volume, tank size, and ambient temperature, so actual water temperature may differ from the set temperature. After cooling, tank water remains stable 1/4 HP High-Efficiency Cooling: The aquarium chiller uses a fluorine-free compressor and R290 refrigerant for efficient cooling. Temperature range: 65-80℉(18-27°C), reducing temperature fluctuations to improve survival rates Large Capacity: This 92Gal chiller meets the needs of various tank sizes, with a high water circulation rate of 1200L/H, keeping the tank at an ideal temperature for your fish. If you have any questions, please contact us for assistance Protecting Aquatic Life: Featuring a corrosion-resistant titanium evaporator, secure for both freshwater and saltwater conditions. Ideal for keeping aquatic creatures like axolotls, fish, shrimp, corals, and jellyfish at the ideal temperature Quick Heat Dissipation: Built-in fan and multiple ventilation holes help dissipate heat from the compressor, ensuring efficient operation. Leave at least 24 inches (60 cm) of space around the chiller for proper airflow and effective cooling
