  • Well for 42 inch Long Fish Tanks -- Active aqua chiller: 11.4'' L x 12.6'' W x 11.4'' H, our water chiller can drop water temperature up to 10F in general. In hot summer, recommended water volume is 80%.
  • Upgraded Accessory -- The fish tank chiller features a stainless steel shaft, thicker wires, and Australian standard plugs. Additionally. However, the water pump in the old fish tank chiller does not come with an Australian standard plug, making it look more beautiful and less likely to blow up sediment at the bottom.
  • Essential for Hydroponics and Aquarium -- High-efficiency freon free compressor provides more rapid and stable cooling than small fans, using r290 refrigerant, circulating cooling without pollution and do not need to be supplemented.water chiller for aquarium can well control the ideal water temp at 68-78F/20-26°C, necessary for creating healthy roots and a good harvest.
  • Tips in Summer -- The standard water volume is 42gal, expecially in hot summer the indoor temperature is too high, the recommended water volume is less than 33gal, the cooling effect will be GREATLY affected by the ambient temperature.
  • Fast Heat Dissipation -- Two built-in fans and a large number of heat dissipation holes on both sides of the aquarium cooler provide powerful ventilation to dissipate compressor heat well, ensuring compressor can work efficiently for all day long. Note there must be a space of 6''/15cm around the chiller for fish tank for enough air circulation and efficient cooling.
