Marina Submersible Heaters are available in a variety of wattages for all sizes of aquarium.

Each has an on/off light indicator for added reassurance and is made with safety glass.

The heaters have a ceramic heater core which means that the heat is distributed evenly and efficiently throughout the aquarium.

These efficient heaters from Marina can be used in both fresh and salt water aquariums.

The smallest Compact 10w heater is suitable for use in smaller plastic aquariums, ideal for kids tanks that you want to make tropical.
