Marina heaters for aquariums are some of the most inexpensive ways to keep your aquarium temperature raised currently available on the market. Part of the larger Hagen group of aquatics and pet companies, they are still of high quality, but can be found here at Swell UK at low prices.
Easy to install with the integrated suction pad on the rear of the Marina fish tank heater, they stick nicely to the inside of your aquarium glass. Available in multiple different sizes and wattage intensities, they are pre-set heaters, so choosing the right one is important for achieving the right temperature.
The fact that they are present makes them both cheaper and more reliable. Less complicated, Swell are able to offer them at cheaper prices, and the lack of complicated circuitry actually makes them a little less likely to break down, a win-win design point!
Perfectly capable of heating tropical aquariums of small and medium sizes to maintain a higher temperature to keep your tropical fish happy and healthy.
