sera guide - Marine aquariums

Tip 23 Most aquarium fish are accustomed to water temperatures about 25°C (77°F). The aquar- ium water must therefore be heated accord- ingly. The aquarium heater must be attached in the aquarium in a way that the water al- ways flows round it, in order to heat the water evenly. The required wattage is very easy to determine: Calculate approx. 1.5 Watts per liter (1 US quart) of water in rooms that are only slightly heated. If the aquarium is placed in a warm room, 1 Watt per liter (1 US quart) of water is sufficient. The heater may without hesitation be chosen in a stronger version; the power consumption for producing a cer- tain amount of warmth is identical. The stick-shaped sera aquarium heaters are entirely water-proof and marine wa- ter resistant. Temperature adjustment is particularly easy due to the adjustment wheel with temperature scale. sera aquarium heaters are available in many appropriately selected wattages from 25 Watts to 300 Watts and are fitted with a protective grid.
