Product overview

Treating your tropical or marine fish to one of these heaters means the lucky things get to take advantage of our in-depth aquarium heater experience and knowledge. And you get to relax at the thought of the 2-year guarantee and excellent safety credentials. These heaters are super-reliable, and thanks to the extra-thick safety glass and plastic end cap, are also extra safe. The positive click-control makes its easy to adjust the temperature precisely, but as the heater is already set to 24u00b0C you might not find you need to.
