Theo Water Heaters
These aquarium heaters are designed for extended use and are completely safe as long as your heater is completely submerged in your solution. It is recommended to place your heater at the bottom of your tank as when these heaters are not submerged they can crack, which leads to exposed filament and electrical shock.
Our Aquarium Heaters are easy to set and precise, coming with their own built in thermostat and the heating element is efficient and compact. These Aquarium Heaters are designed for extended use and are supplied with suction cups and support clips.
Please note: The ideal temperature for your nutrient solution is between 18 – 22 degrees Celsius. Lower than 18 degrees will slow your rate of growth, higher than 22 will create an environment conducive to infection.
