Struggling to choose the right aquarium heater for your tank? Try out our Aquacadabra top tip: in today's modern centrally heated homes, a good guide for heater size is to match the volume of water in litres to an equivalent heater in watts. For example, if your aquarium is 25lts, a 25w heater would be suitable, for an aquarium of 300lts, use a 300w heater. If you're still not confident making a decision, feel free to reach out to our friendly experts, who will be happy to guide you to the best option for you.
