I have been keeping aquariums Pumps since I was a kid. With time I understood it’s not only about fish but about the way you feel when you are around them. I love nature, green technology, and coffee.
One of the key components of a successful aquarium is a stable water temperature. When the water temperature is below the recommended level, fish and plant metabolism slows down. Sudden drops in temperature are especially stressful to fish. Low temperature inhibits the fish’s immune system and may lead to disease problems.
Most tropical fish like tetras, rasboras, cichlids and even bettas need warmer water parameters, and therefore will require a heater.
Best Heaters for Nano Aquariums
This tiny heater works for marine and freshwater nano aquariums, betta tanks, for example.
The design is based on the traditional glass tube with a wound metal heating element. Think of it like a traditional glass heater, only much smaller.
There is no temperature adjustment knob. Instead, the Pulaco uses a pre-set temperature rated to keep tanks up to 6 gallons at 78°F.
The heater has an LED light that is green when the heater is powered up and red when heating the water.
The heater attaches to the side of the tank with a suction cup and must be positioned vertically in the tank.
The power cord is four feet long. The heater measures five inches long.
The Nicrew heater steps away from the traditional glass tube design.
The heating element is encased in a plastic polymer body. This makes the heater unbreakable.
The temperature is pre-set to 77°F (25°C), making it suitable for freshwater tropical and marine tanks. The heater is available in 15 to 75 watt models.
