Fluval M50 Ultra-Slim Submersible Aquarium Heater – 50W Underwater Heater for Aquariums up to 15 Gal.

Très bon chauffage, aucun regret sur son efficacité

Toller Heizstab! Kann ganz unter Wasser gesteckt werden. Schaltet ab und an den Sensor ein, um die Temperatur zu überprüfen. Seit einem Monat im Gebrauch und die Temperatur bleibt konstant. Gut verarbeitet.

Cable is short.

I love this heater. I have been using it in my betta's tank for about a year, and so far, it has worked very well! This heater is not made for being completely submerged under water. The black and grey part (the part above the little wavy marks) must be above water, along with the cord. I put this heater right next to my filter so that the filter motor can move the warmed water around the aquarium evenly. This heater is, of course, automatic. It has a thermostat somewhere in it that tells it to turn on when the water is too cool and turn off when the water gets warm enough. When the heater is warming your tank water, there will be a blue light on the side, and when it turns on and off, it will make a clicking sound and the light will turn on or off. This is a very good heater for my five-gallon tank. I have it set at about 81 degrees, and it keeps my tank at a steady 78 or 79 degrees Fahrenheit (which is the perfect temperature for betta fish). I am very impressed!

Utilizo num aquário com 3 pequenas jovens tartarugas...correto grau de temperatura em relação ao escolhido...pode ser considerado excessivo para o meu pequeno aquário 40x20x17), mas cansei-me de comprar outros mais baratos, com tamanho menor, mas que tinham problemas com a efetiva temperatura da água: divergências quanto a graus de temperatura da água e a selecionada/indicada
