Aquarium Heater Holder
A heater holder is the perfect item for positioning and holding an aquarium heater. Such heater holders can be adjusted to suit different sized heaters. Twin suction cups secure the heater to the aquarium glass.
New aquarium heaters are sold with a heater holder but with time these will deteriorate and become unuseful. These items can also be useful for securing other items inside of your aquarium such as sponge filters and other light aeration devices.
