25W Adjustable Submersible Heater Fish Tank Aquarium Freshwater Marine

This heater is made of Quartz Glass, which is high temperature resistance, anti-corrosion, anti-explosion. With dual Isolation Design, as the glass sealed the internal structure from water that it is harmless for the aquatic organisms and fish without leakage when fully submerged. Adaptable in both freshwater and sea water.With nickel chromium heating wire, water temperature rise rapidly due to the good heating effect and thermal conductivity. When completed, temperature will keep constant automatically. Sensitive and reliable thermostat maintains uniform temperature, no temperature fluctuations.Temperature is adjustable with a high accuracy that it can be flexible to meet varied submersible environment demands（20-34℃/68-93℉）. Fully submersible heaters with two suction cups work in any position (horizontal or vertical) to provide optimum aquarium water temperature.
Features
Anti-Explosion:The main body of the heater is made of Quartz Glass, which is high temperature resistance, anti-corrosion, anti-explosion. With dual Isolation Design, as the glass sealed the internal structure from water that it is harmless for the aquatic organisms and fish without leakage when fully submerged. Adaptable in both freshwater and sea water.
Fast Heating:With nickel chromium heating wire, water temperature rise rapidly due to the good heating effect and thermal conductivity. When completed, temperature will keep constant automatically. Sensitive and reliable thermostat maintains uniform temperature, no temperature fluctuations
Adjustable Temperature:Temperature is adjustable with a high accuracy that it can be flexible to meet varied submersible environment demands（20-34℃/68-93℉）. Fully submersible heaters with two suction cups work in any position (horizontal or vertical) to provide optimum aquarium water temperature.
Safe Guard:There will be a cover guard accompanied with the heater where fish won’t be burned from. Automatic shut off when the temperature is reached.
