Your tank’s personal climate manager. This cooler keeps 42-gallon aquariums (that’s your standard 42”x12”x18” setup) perfectly chilled even when summer heat hits. Using planet-friendly R290 refrigerant (no Freon!), it cools way better than old-school fan systems - dropping temps by 8-10°F in hot weather to maintain that sweet 68-78°F range fish love.
